In the eligibility form if i check "Enrolled in an accredited academic institution or official homeschool equivalent" i am required to select also a STEM organization even if that part should be optional. Is it a bug or something? I’m Enrolled in an accredited academic institution but not in a STEM organization

I was watching the Collaboration with messages session, but i'm unble to find any more references to that API. At the bottom of the video description it says that the API will be available in the next betas. Are there any news?
