Autodesk Forge App config; how to set multiple callbacks?

Question

I have a new Forge App and it works for retrieving OAuth token for the one configured site (local, currently). Their documentation says that you can configure multiple callbacks for an app, but I only saw room for the one, and there were no examples. Can I just list them all separated by semicolons, or other punctuation?

When I did this exact same thing with configuring a Procore App, they had a text box and it was clear and easy to enter multiple callback locations. Forge, not so much.

Thanks in advance!

I have not experimented with trying to add multiple callbacks on one line because those environments are not ready yet for testing (but I would prefer to know the correct technique before proceeding!)
