Onlyoffice self hosted community version setup

Nextcloud version (eg, 18.0.2): 19.0.4
Operating system and version (eg, Ubuntu 20.04): docker container
Apache or nginx version (eg, Apache 2.4.25): nginx 1.18.0
PHP version (eg, 7.1): 7.3.24

The issue you are facing:

My understanding is that Nextcloud is supposed to have the option for a self hosted version of Onlyoffice. Under Settings - Administration, there should be a Onlyoffice option.
I do not see that option in my Nextcloud instance.
I know about the Community Documents app, but I do not want to use it.
I would prefer to host my own version of only office. Right now I’m using collabora and it has gotten horrible over the last year.
Can someone point me in the direction where I enable this option?

you install this app:
then you have the settings under: /index.php/settings/admin/onlyoffice

There are two parts to make Nexcloud to work with OnlyOffice - the OnlyOffice connector
that ALWAYS needs to be installed and the OnlyOffice server.

The latter can be of two “flavours” - standalone and Community Document (that you don’t want).

I see it was the difference between capital and lower case letters when searching for the app.
