How to add custom button on a sub panel record list ?

I need some suggestion in my suite CRM module integration. I have a sub-panel in one of my modules and required to add one more edit button to redirect to a custom form to take some input from the user for each row separately.

In the above image on click of the edit button of a row, there is a remove button, I want to add one more custom button after remove and need to redirect from there to my new form.

I have checked some of forums and blogs but didn’t found the solution, pleases share some suggestions.

There is a sample on this post:
