Opening/linking to an app

AppSheet AppSheet Q&A
1

Does anyone know how to send the user to an additional app on iOS when a user clicks on a table-based URI/URL in app sheet.

I am trying to send the user to the What3Words app using the following syntax contained within an AppSheet table:

“ w3w://show?threewords=index.home.raft”

It is not possible to open an arbitrary app or non-common URL scheme from AppSheet.
