Extend Wix Widget Panel in Custom Widgets

Question:
Can I extend Wix Widget Panel in Custom Widgets created via CLI?

Product:
Wix Editor, Wix Studio Editor

What are you trying to achieve:
Hi, I want to build custom text widget that extends Wix Text Widget. I want it to work the same way as Native Text Widget does, but with some additional functionality.

What have you already tried:
I already built my custom feature but it’s missing core features like style, font size aligning etc. I can of course use some components from Docs but maybe there is better and easier way. The other problem would be probably accessing site themes if building everything from scratch.

Additional information:
I am building my widget using Wix CLI (React)
