Salesforce - How to redirect Community Cloud user to its related Account?

Today I got a following requirement for a Community Cloud:

Can we have a link in a community header or navigation bar or menu, that will redirect user to its related Account? So that we show his Account details?

We couldn’t do a static link, as Account Id is always different.

For community users there are AccountId (and ContactId) fields on User object. So I thought it’s easy – I’ll get AccountId from User, and expose it via Lighting Component which will then make a redirect.

Community custom page has been already created – it was just about creating LWC and putting it there.

I started with Apex Class which gets Account Id for logged in user.

public with sharing class AccountRedirect {
    @AuraEnabled(Cacheable=true)
    public static String getAccountId() {
        User user = [ SELECT Id, AccountId FROM User WHERE Id = :UserInfo.getUserId() ];
        return user.AccountId;
    }
}

and then I created LWC for it. Template:

<template>
    Redirect in progress...
</template>

and JS controller

import { LightningElement, api } from 'lwc';
import { NavigationMixin } from 'lightning/navigation';
import getAccountId from '@salesforce/apex/AccountRedirect.getAccountId';

export default class AccountRedirect extends NavigationMixin(LightningElement) {

    connectedCallback() {
        getAccountId()
            .then(result => {
                if (result !== undefined) {
                    this[NavigationMixin.Navigate]({
                        type: 'standard__recordPage',
                        attributes: {
                            recordId: result,
                            objectApiName: 'Account',
                            actionName: 'view'
                        }
                    });
                }
            })
            .catch(error => {
                console.log('error', error);
            });
    }
}

and added tags to xml to make sure to expose it on a Community Page

<lightningcomponentbundle xmlns="http://soap.sforce.com/2006/04/metadata">
    <apiversion>53.0</apiversion>
    <description>Account Redirect</description>
    <isexposed>true</isexposed>
    <masterlabel>Account Redirect</masterlabel>
    <targets>
        <target>lightningCommunity__Page</target>
        <target>lightningCommunity__Default</target>
    </targets>
</lightningcomponentbundle>

I got an error saying a community profile didn’t have access to apex class. Once I granted access – it worked, user was redirected.

But then I had a thought:

Is it possible to do it only via LWC, without Apex code?

Then I could get rid of apex class, unit test and no need to modify the profile.

So I ended up with this js controller code:

import { LightningElement, wire } from 'lwc';
import { NavigationMixin } from 'lightning/navigation';
import { getRecord, getFieldValue } from "lightning/uiRecordApi";
import ACCOUNT_ID from "@salesforce/schema/User.AccountId";
import USER_ID from "@salesforce/user/Id";

export default class AccountRedirect extends NavigationMixin(LightningElement) {

    @wire(getRecord, { recordId: USER_ID, fields: [ACCOUNT_ID] })
    wiredAccount({ error, data }) {
        if (data) {
            if (data !== undefined) {
                let accId = data.fields.AccountId.value;
                this[NavigationMixin.Navigate]({
                    type: 'standard__recordPage',
                    attributes: {
                        recordId: accId,
                        objectApiName: 'Account',
                        actionName: 'view'
                    }
                });
            }
        } else if (error) {
            console.log('error', error);
            this.error = error;
        }
    }
}

I worked perfectly well:
