What are the online tools for collaborative editing of texts on the site?

Question

Distant work

There is a task: an employee makes changes to the text on the site, his edits are visible to other people. It is possible to accept edits, reject, write comments.
Approximately the same as in google documents, only for sites.
Naturally, all this is not visible to the average visitor to the site.
Clarification: this is not a CMS feature, this should work with any site on the web, regardless of the editors' rights to it.

Answer 1

depending on cms, there are built-in tools (separation of rights). in the same joomla. there are levels AUTHORS, EDITORS, MANAGERS, etc.

Answer 2

You can configure access to the google drive file only for specified profiles. Those who need it will have access. The rest are closed. Additional functionality can be found in add-ons

Answer 3

There is such a thing , but the changes are visible only to one person.
In general, what you want does not exist.
