I need help using the Synth V Plugin with Sibelius or Finale.

Has anyone had any luck getting the Synth V plugin to work with Sibelius or Finale? I’ve tried it in both programs with no success. Finale makes a kind of stuttering sound and then plays a split second at the end. Sibelius speeds through the piece at lightning speed and doesn’t make any sound. I’m usually quite good with these sorts of things and have followed all the instructions for making a plugin work. Does anyone have any advice? Thanks so much. (I have a MacBook Pro (14-inch, 2021) with Apple M1 Pro chip and my OS is Monterey 12.6.)
