Show only the actual user data

Hello Brad,
Are you talking about this tutorial: https://community.wappler.io/t/getting-details-of-the-logged-in-user-and-binding-them-to-your-page/2850 ?, the problem is that in this tutorial I am able to show who is logged in. But that I need is that if I am a seller and my seller ID is 999 when I get in the clients list data, I only see the clients where the seller is 999 (My Seller ID), anything else will not be show to me.
