Hi @Melisa Martínez and welcome to the Community.
There's only one way to find out ... try it :)
It works with Google docs, for example.
If it doesn't work, you can go old-school and try embedding via the iframe macro on a regular page. You can achieve very good results with presentation decks, figma designs, etc. I wrote a how to article as some of the tools require a little hack to work but it's worth trying.
In any case, the actual visibility within Confluence depends on access rights/permissions to the linked document - whether a Smart Link or iframe.
For example, I can embed company-only stuff from Google because both Confluence and our Google site are behind the same SSO.
