How can I get custom related list records in LWC?

Question

I am trying to use getRelatedListRecords, it is working well with standard object, so I am getting related Contacts of Account record successfully but I cannot get related Xy Recipes records(object api name: XyRecipe__c, Tab name plural: Xy Recipes) so do I need to activate anything i Salesforce to make use of custom related list or why I am not able to use it just like Contacts list successfully? here is the code:

import { LightningElement, api, wire } from 'lwc';
import { getRelatedListRecords } from 'lightning/uiRelatedListApi';

export default class Xy_recipes_lwc extends LightningElement {
    @api recordId;

   @wire(getRelatedListRecords, {
       parentRecordId: '$recordId',
       relatedListId: 'Xy Recipes',  
   }) agendaExceptionsHandler({data, error}) {
       if(data) {
           console.log('Response for getrelatedrecords: ', JSON.stringify(data));
       }

       if(error) {
           console.log('Error from getRelatedList 4: ', error);
       }
   }
}```

Answer 1

I was facing same issue. Adding __r fixed the issue.

@wire(getRelatedListRecords, {
    parentRecordId: '$recordId',
    relatedListId: 'Todo_List__r',
    fields: ['Todo_List__c.Id','Todo_List__c.Name']
}
