Collabora online - install help pls

Good afternoon, please tell me about editing documents online. Interested in doc and excel. I installed Collabora Online - Built-in CODE Server, but it writes the following and does not allow me to set the settings of the collabor server, which was created on another one.
The built-in CODE server is designed to work with the regular Collabora Online app. Install this from the Nextcloud App Store.
If I put the Nextcloud office, then everything starts to lag terribly and I don’t know what settings it needs to make so that everything is not so bad.
