Hi @Phineas
Let's simply the steps and destruct what you are trying to achieve.
1. Create one more child web page> below the list web page

2. On the newly created view web page add a Form in the middle of the page. ( possibly with in a one-column section)
3. Select the form > and in the right panel. Choose your table and view ( Create new if existing is not available)

4. On the first entity list page > Select list and on the right panel option and set the view details to point it to the newly created view webpage. screenshot below

If the above setup is working, then you can continue using this in the same way which will open up a new web page when the view details button is clicked.
If you don't prefer to render on the web page, then switch to form which will load a modal.
Hope it helps.
