@hugetim Thanks for the reply.
You are not way off. We use colab regularly here and I spent quite a while considering it for this purpose. It turns out, as far as I can tell, that you cannot embed a colab notebook in an iframe. If I could, I think I would have just about everything I need for this app.
I even tried using an iframe component that meredydd created.
Again, I could be missing something, but this what I understand at the moment. I’m certainly open to other approaches as well.
