Image Upload Instructions

Has anyone managed to upload photos to xano?
I have done all the back end in xano and have an endpoint url - But I’m a bit lost trying to do this from Appgyver.

There is no complete instructions in Appgyver for file upload. Plenty of bits and pieces in the forum, but I’m finding it impossible to follow. When I google, it seems some of the appgyver documentation doesnt exist anymore, since going to SAP.

Can anyone point me in the right direction please. Thanks.
