[SOLVED] How to query "Members/PrivateMembersData"?

My process is search first if a Member already exists using the email.
If the Member already exists, then its automatically assign it a Role.
If the Member does not exists, then its automatically registers it, then, assign it a Role.

I am having trouble performing a query using the email to check if the Member already exists and get its Member ID.

Below are my codes:

//FRONT-END:
import wixLocation from 'wix-location';
import {myRegisterMemberFunction} from 'backend/autoRegisterMembers.jsw';
import {assignRole} from 'backend/rolesVolunteers.jsw';
import {findEmail} from 'backend/findMemberEmail.jsw';
    
$w.onReady(function () {
    $w('#applyBtn').onClick(function () {
        let emailP = $w('#emailAddP').value;
        let passwP = $w('#passWordP').value;
        let options =  { 
            contactInfo: {
            "firstName": $w('#firstNameP').value,
            "lastName": $w('#lastNameP').value,
            },
            "privacyStatus": 'PUBLIC'
        }
    
        findEmail(emailP)
        .then((results) => {
            if(results !== null || results !== undefined) {
                let userId = results; 
                console.log(userId);
                assignRole(userId);
            }
        });
    });
});

//BACK-END:
import wixData from 'wix-data';

export function findEmail(email) {
    return wixData.query("Members/PrivateMembersData")
    .eq("loginEmail",email)
    .find()
    .then((result) => {
        return result.items[0]._id;
    })
    .catch((error) => {
      console.log(error);
    });        
}
        

This is the error message in the Logs:

"["Permission denied: {\"message\":\"permission_denied, details: {\\\"RequiredRole\\\":\\\"Member\\\",\\\"GivenIds\\\":\\\"visitor -> a3d80916-f2ae-4981-a8d3-4c1b1a71ce56\\\"}\",\"details\":{\"category\":\"api_error\",\"error\":\"permission_denied\",\"requiredrole\":\"Member\",\"givenids\":\"visitor -> a3d80916-f2ae-4981-a8d3-4c1b1a71ce56\"}}."]"

Its is causing an error in my Back-End code, line 3 on this part: " return wixData.query(“Members/PrivateMembersData”)"

You have no permission to be able to query the data.

Try the following…

let options = {
  "suppressAuth": true,
  //"suppressHooks": true
};

wixData.query("Members/PrivateMembersData", options);

The wixData . query only requires 1 argument. It produces an error if I include the options.

I created a work-around to solve this problem.
