This is a simple plugin that I have written to install the following TinyMCE plugins (not to be confused with WordPress plugins) to your TinyMCE toolbar:
<ul>
<li><a href="https://www.tiny.cloud/docs/plugins/autosave/" title="Autosave plugin | Docs | TinyMCE" rel="nofollow ugc">Autosave</a></li>
<li><a href="https://www.tiny.cloud/docs/plugins/fullscreen/" title="Full Screen plugin | Docs | TinyMCE" rel="nofollow ugc">Full Screen</a></li>
</ul>
There are no settings or anything for this plugin. Just install it and away you go!

Add AutoSave | Fullscreen to TinyMCE

This adds the AutoSave and Fullscreen plugins to your TinyMCE toolbar.

By activating this plugin autosave feature in the Gutenberg editor will be disabled. Alternatively it also provides options in the editor to select a different autosave interval time than the default 60 seconds.
The block editor will still use local autosave that saves a copy of the edited post to your local storage and allows you to restore it if you happened to navigate away without saving. This plugin prevents the editor from making periodic requests to “*/autosaves” REST endpoint, which disables the “Update” button of the editor, typically at the exact moment you’re trying to click it.

Disable Gutenberg Autosave

Allows to control Gutenberg autosave interval or disable autosave completely.
