**Describe the bug**
just spun up nc23 the other day via docker containers(fpm-ā¦nginx with caddy reverse proxy on host). Itās running fine
It has collabra core and collabra app included. Both are enabled and Iāve selected the core in the settings.
NC seems to know the file types (e.g. .odt) as when you make a new file that is a choice.
But if you then open the file (in the browser ui, single click) instead of opening collabra libreoffice with that file it just wants to download it like it would any unknown file type.
Note: Markdown works. if you click on .md file it opens in the markdown editor so other file types are opening their app
Not sure what setting/setup Iām missing here but itās not working āout of the boxā.
**To Reproduce**
See above. spin up nc23 docker. Enable collabra core, create a odt document, attempt to open doucment, NC tries to download document instead of opening embeded collarbra with the doucment
**Expected behavior**
Should open the odt document in collabra (libreoffiece) app embeded in NC web UI like other know document types (e.g. .md)
**Screenshots**
