Greetings self hosters!

I’m looking for suggestions on a document management service.

I currently use next cloud (AIO) to live collaborate, edit, and store my documents, but I want to be able to embed them in my WordPress site. Currently this is impossible to do nicely with nextcloud.

Do you happen to know of a self hostable document sharing solution that allows me to use the next cloud WebDAV credentials and embed those documents into my WordPress pages? Also if there is a full text search functionality that I can also embed into WordPress?

Any suggestions would be great! I am testing filestash.app and it works, but its not super reliable and does not offer a built in full text search despite the tin claim.

What would you do?
