How to create a working Owncloud system that has a working online office editor?

It’s easy enough to set some variables when installing it and get a working file server, but not working with OnlyOffice. Google Gemini just seems to spin in circles when helping me troubleshoot it. Now, I’m desperate. Can you give me a step by step guide that will actually work for me?

@pixer415 Maybe you can refer to https://github.com/bigbeartechworld/big-bear-casaos/blob/master/Apps/onlyoffice/docker-compose.yml. I hope it will be helpful to you.
