Connecting account with a post on Wix

I am using Wix to create my site, and I would like to know how to connect a user account with a post they made. For example, I’m creating a feature where users can submit data to a CMS, such as a dog’s name and a video of their dog. When they click to submit the data, it should be displayed on a page where the dog’s name and video can be viewed by everyone. However, only the creator of the post should be able to edit or delete it.

I’ve already created the ‘CMS form page’ with inputs for the dog’s name and dog video. When I click to submit the data, it goes to another page where all the data I create using the form is displayed for everyone.
