Unfortunately, since Script Apps have to be run in the client of an open base, Airtable does not allow buttons connected to Script Apps to be used outside of the client base. They are always disabled.
Buttons that do simpler things, like open a URL, are enabled and work in embedded Views.
You may be able to find a work around that involves an Automation Script triggered by some simpler action from the button.
The most simple solution I can think of, although it may be clunkier than you are wanting, is to have the button open a URL for a form that the user submits to this other table you have.
