I am trying to find the edit button which is present in workspace in ui actions or action assignment, is there any other way to find them in servicenow, please find the button available on workspace in screenshot.

This is looks fine to me but in my case, i wanted to configure the same Edit button functionality to procurement case list of records in procurement workspace. and i have copied the same button from action assignments on the procurement table but i could not see it on workspace.

And under Action Assignments you created an entry for your procurement table?
