Linux Seafile with Hiawatha Reverse Proxy and OnlyOffice Integration

I’m currently running Seafile CE & Seahub (with TLS on a subdomain) on Archlinux without any problems. I use Hiawatha webserver as a reverse proxy. Recently, however, I’ve been trying to integrate the OnlyOffice docker with Seafile in order to edit documents. The documentation for Apache and Nginx is great, however, I’m having trouble incorporating it with Hiawatha. This is a Hiawatha + OnlyOffice problem and not Seafile, but I’d like to know if anyone else has already invented this wheel and is willing to share what they’ve learned.
