Custom themes in Wappler 7

I'm thinking to buy custom Bootstrap 5.3 theme and I couldn't find a proper step-by-step instruction how to import it to Wappler. Maybe I missed some, but this almost 5 years guide looks a bit outdated - Theme Manager

Is there any plans to improve theme management in Wappler 7 or publish up-to-date guide?

Thank you in advance.

The way theme manager works is the same as described in this docs. The only difference between Wappler 6/7 and this guide is the Wappler UI, the rest is the same.
Probably the article you're looking for is this:

It's the same for bootstrap 4 and 5.

Yes, this is the one I've been looking for.
Thank you.
