Guest User not able to see Contact Record in LWC

Question

I have an LWC component which is used to display contact information to guest user, using which they can also update the contact details.

When I'm running that LWC component as a system admin, I can see the field values, but as a guest user, I can't see any value.

I have already given class and object access to guest user profiles, also FLS permission is given for all fields.

HTML:

<template>
    <lightning-card>
        <div class="slds-m-around_medium">
            <lightning-input type="text" label="Name" value={Name}></lightning-input>
            <lightning-input type="text" label="Custom Field" value={CustomField}></lightning-input>
        </div>
        <div>
            <lightning-button label="Save"></lightning-button>
        </div>
    </lightning-card>
    
</template>

JS:

import { LightningElement , wire, api, track} from 'lwc';
import { getRecord, getFieldValue } from 'lightning/uiRecordApi';

import CONTACT_OBJECT from '@salesforce/schema/Contact';

import CONTACTNAME from '@salesforce/schema/Contact.Name';
import CUSTOMFIELD from '@salesforce/schema/Contact.CustomField__c';

export default class UpdateDealerSocialMedia extends LightningElement {

    @api recordId;
    @track record;
    @track error;
    @track nameValue;
    @track customFieldValue;

    
    @wire(getRecord, { recordId: '$recordId', fields: [CONTACTNAME,CUSTOMFIELD] })
    wiredAccount({ error, data }) {
        if (data) {
            this.record = data;
            console.log('>>> record... '+JSON.stringify(this.record));
            this.error = undefined;
            this.nameValue = this.record.fields.Name.value;
            this.customFieldValue = this.record.fields.CustomField__c.value;
        } else if (error) {
            this.error = error;
            this.record = undefined;
        }
    }
    
}

I feel your pain, according to the new Guest User security, there's a lot less one can do through UI now, here's a good summary: https://help.salesforce.com/articleView?id=networks_guest_policies_timelines.htm&type=5

• For external user to View a record, you need to add a sharing rule, which has a new option now: Guest user access, based on criteria *Note that Guest user can no longer be owner of any records, so you can set your sharing rule to "Created By", or something else other than Owner Id.

• And if you want to Edit / Delete record, it would have to be apex, (without sharing) https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_keywords_sharing.htm , which runs in system context.

Also, an alternative method: Flow(Without Sharing) is mentioned here: https://www.isimio.com/2020/08/07/migrating-to-salesforce-secure-site-guest-user/
