I would like to create an SQL Server Management Studio v18 extension that opens from the execution plan window. I believe that this is technically possible because there is a third party tool that already does this:
So far, I've been able to create a basic extension in SSMS v18 using the guide located here. I was also able to move the placement of the button by referencing the IDs in the documentation. However, I can't figure out how to modify the .vsct file in order to move my button to be within the execution plan window.
How can I create an SSMS extension that opens from the execution plan window?
