Brett,

It would look like this:
PS. Make sure to change .eq(’ emailField ', userEmail) → the emailField value here to your actual database field value.

import wixUsers from 'wix-users';

let user = wixUsers.currentUser;

user.getEmail()
  .then( (email) => {
    let userEmail = email;      // "user@something.com"
    
    wixData.query('YourCollectionName')
      .eq('emailField', userEmail)
      .find()
      .then((res) => {
          if(res) {
              console.log('Duplicate user found, returning');
              //below is error messages to show
               $w('#error').show(); 
               $w('#errorText').show(); 
          }
          //insert to collection here (no duplicate found)
      })
  } );

Hope this helps,
Majd
