Connecting teachable machine with app inventor

Hello,
I am a middle schooler student, studying programming.
I am trying to make an app for project, identifying the pose.
So, I want to utilize teachable machine, but I don't know how to connect it with app inventor.
How can I use pose extension?

And is it available to use microbit with app inventor?
