Inline Actions in a child table

I am trying to set up an inline action in my child table within a form. I read in the community how to do it. The action even shows up in the detail view outside of the form. But it wont show up within the form itself. THere must be a button or setting I have disabled. Here is a video

Actions are not available INSIDE of a form.

Records can be edited by a form OR by an action (outside of a form).

There are several column settings that will present ‘buttons’ in Form-View, but these are not Actions.

Instead of Actions, you may want to explore the column settings for each column of your form where you want some kind of button. There are lots of options depending on the column-type.
