Hey,
You can try using the ability to filter by logged in user - https://support.wix.com/en/article/how-to-filter-a-page-based-on-the-currently-logged-in-user
The main thing to note there is that this solution uses the “owner” field, which, in your use case, will be your own user as you’re the one adding the content. So you’d need to modify the owner field to reflect the the user’s.
