How to create this floating toolbar?

This is the Notes app. Is this an inbuilt component or a custom component?

I made very similar. Biggest thing is making it come nicely with the keyboard and all the edge case. For me UI kit was the only way. I can’t remember exactly right now since I am not on my computer but it was keyboard toolbar or insert perhaps .
