How to display related records in Salesforce using Lightning Web Component?

lightning/uiRelatedListApi can be used to fetch the related records and display using Lightning Web Component. Since we use lightning/uiRelatedListApi, apex code is not required to fetch the related records. Check the sample code below:  

Sample Code:
HTML:

<template>
    <lightning-card>
        <div class="slds-m-around_medium">
            No of Contacts is {recordCount}<br/><br/>
            <lightning-datatable
                key-field="Id"
                data={records}
                columns={columns}
                hide-checkbox-column="true"
                show-row-number-column="true">
            </lightning-datatable>  
        </div>
    </lightning-card>
</template>

JavaScript:
import { LightningElement, wire, api } from 'lwc';
import { getRelatedListRecords } from 'lightning/uiRelatedListApi';
 
const COLUMNS = [   
    { label: 'Name', fieldName: 'Name' },
    { label: 'Email', fieldName: 'Email' }
];

export default class RelatedListComponent extends LightningElement {

    @api recordId;
    recordCount;
    records;
    columns = COLUMNS;

    @wire( getRelatedListRecords, {

        parentRecordId: '$recordId',
        relatedListId: 'Contacts',
        fields: [ 'Contact.Id', 'Contact.Name', 'Contact.Email' ]

    } )listInfo( { error, data } ) {

        if ( data ) {

            console.log( 'Data is', JSON.stringify( data ) );
            let tempRecords = [];

            data.records.forEach( obj => {

                console.log( 'obj is', JSON.stringify( obj ) );
                let tempRecord = {};
                tempRecord.Id = obj.fields.Id.value;
                tempRecord.Name = obj.fields.Name.value;
                tempRecord.Email = obj.fields.Email.value;
                tempRecords.push( tempRecord );

            } );

            this.records = tempRecords;
            this.recordCount = data.count;
            console.log( 'Records are ' + JSON.stringify( this.records ) );
            
        } else if (error) {
            
            this.records = undefined;

        }
    }

}

js-meta.xml:
<?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata">
    <apiVersion>52.0</apiVersion>
    <isExposed>true</isExposed>
    <targets>
        <target>lightning__RecordPage</target>
    </targets>
    <targetConfigs>
        <targetConfig targets="lightning__RecordPage">
            <objects>
                <object>Account</object>
            </objects>
        </targetConfig>
    </targetConfigs>
</LightningComponentBundle>


Note:
I have configured the Lightning Web Component page in Account Lightning Record page.
