is it possible to use UPDATE API on UI Designer?

Hello,

i'm a intern in a company that makes applications with bonita studio, and we recently started using this program, so not many people know how it fully works on what can we do with it and what we can't.

I was trying to make a connection with a UPDATE API to edit a human task, so i could reassign the task to someone else in my custompage/applications for user/manager. The problem is I tried to use a button with the PUT method but it doesn't seem to work, is it even possible to use this in UI designer or do I need to implement this on a connector via bonita studio?

Thanks for your time!

:)
