Blackmagic plugin not apears in MEDIA MENU

Hello, good morning. I am a Mac user and have UR 5.71 installed. Due to improvements in the Composure module, I usually use a Blackmagic card. I have installed the Blackmagic Player plugin, and “Blackmagic Media Output” and “Blackmagic Media Source” should appear in the media menu of the content browser, but they do not. I have reinstalled the software and made sure that the plugin is activated, but it does not appear in the media menu. Does anyone know why?

Ndi was added in 5.7 and we are hoping to add blackmagic in a future release for Mac.
