Error: App “documentserver_community” cannot be installed because appinfo file cannot be read

Hi,
I need a little help as my OnlyOffice connection has stopped working. I’ve been trying to uninstall and reinstall the community document server and onlyoffice, but I am getting the error: App “documentserver_community” cannot be installed because appinfo file cannot be read.
I’ve looked through the forums and found this as a possible solution
Continuing the discussion from Cannot install documentserver_community app - appinfo file cannot be read

but I have a snap installation and I do not think the client.php file is there.
I’ve found it in 2 other places under /snap/nextcloud/24018/… and /snap/nextcloud/24051/…
but that doesn’t feel right and these files are read only so I can’t edit them.

Anybody able to help set me on the right path?

Best regards
Psi
