New user Bootswatches access in 4.01

I have picked Bootstrap 5 and one of the Bootswatches. I don’t see how to access this. I went to the Bootswatch site and copied the code for a Nav bar and just pasted it in and that works fine, but I don’t seem to be able to do it from scratch. I’ve looked at all the documentation on Wappler and even searched through YouTube and the documentation does not match or work like what I am seeing in the interface. Is there new, updated docs somewhere? I am still in the evaluation phase, so maybe the functionality isn’t the same? Totally swimming here and I haven’t even tried the deeper stuff like databases and whatever. Jeez.
