How to fetch all individual forms of a specific form type

Hello,

I am looking for a way to get all issues that a specific form is used on.

Currently the only approach I found would be to use ‘GET form index’ on each individual issue to check if it has the form that I’m looking for.

That would mean a lot of requests, and I struggle to believe that this is the most efficient way.

Any suggestions welcome.
