How to embed my latest toots in external page?

I would like to embed my latest toots as a sidebar in an external page, as I do for my Twitter feed here: https://nescolet.tumblr.com/

Not sure about what kinds of things you can embed in tumblr, however a couple of simple options.

Firstly if you can embed an RSS feed then you can use: https://server.domain/@username.rss

And that should give you your latest toots as an RSS feed.

Failing that look into something like https://www.mastofeed.com/ which will give you an iframe which could also work.
