Moving UI prototype files from Bootstrap Studio

Hi,

I have built a UI prototype for my application in Bootstrap Studio. I would like to move this prototype to PyCharm for actual development.  Is there a way to do this, i.e. migrate my UI from Bootstrap Studio to PyCharm?

If not, how can I develop a UI in PyCharm and build the app end to end in PyCharm?  I was unable to find any UI tools; am I supposed to install any plug-ins?
