Hi again,
Basically when you send data to a page, Bubble just adds the unique ID of the element after the URL. The targeted page is then populated with the object with this unique ID.
ex: yourapp.bubbleapps.io/version-test/music_page/14928791234x9394824230 could be an URL generated by the action you mentioned.
Recently, Bubble introduced the “Slug” feature allowing one to reference to an object with a “readable” unique text instead of its unique ID (-> New Slug Feature for Customizable URLs)
ex: let’s say you have a music object whose Slug is “awesome-rock-music” then you can populate your page music_page by entering the following URL : yourapp.bubbleapps.io/version-test/music_page/awesome-rock-music
Hope this helps,
Arthur
