Connecting collabora with wopiserver

[osdaeg]

Hello.
I'm trying to install Collabora for local use, without internet access. Since I didn't want to install Nextcloud, I started looking for Wopi servers and found yours. I already have Collabora and WopiServer installed in Docker. If I access Collabora via IP:Port, it says "OK."
Now I want to connect Collabora and WopiServer, but I don't know how.

Could you help me?
I used a Docker Compose file to set up both services.
How do I proceed from here?

Thank you very much!

Hello there, this question is very similar to #42

If you are ready to experiment and are OK with a non-production setup, you'd have to trigger the open workflow for a file available in the wopiserver local storage.
