Hey Bidfix,
So you can simply paste this code above in your page or site code to solve the problem:
import wixData from 'wix-data';
import wixUsers from 'wix-users';
$w.onReady(() => {
let user = wixUsers.currentUser;
let userId = user.id;
wixData.query("PostBids")
.contains("title", userId)
.find()
.then(() => {
$w("#dataset1").setFilter(wixData.filter()
.contains("title", userId) );
