Bitmoji Classroom

I would like information on how to link a Kami assignment into a slide so the link takes the student directly to the assignment.
The assignment is posted in the Google classroom as a Kami assignment already, and I’ve tried using that link but it does not go to the lesson. It takes the student to the Classwork page.
Ive also tried clicking on the Kami lesson and using that link but it gives them an error message.
The Bitmoji Classroom is basically a Google Slide so Im not sure why it will not work. Can some one please help?
