Hello,

Can you please help me add a custom button on the Payments tab of the Sales Order screen?
In which extension should the new button be created?
When I try to add it in the Sales Order extension, I get the following error message.

I don’t see any code snippets, what part are you getting stuck on? Did you create the action and you are just trying to add it to the Payment tab instead of the header?
