Create TikZ pictures within draw.io

Is your feature request related to a problem? Please describe.
It's cumbersome to use TikZ pictures within draw.io because:

1. I need to author the TikZ pictures in a separate program
2. I need to compile them to an image format and import them into draw.io
3. I have to save the TikZ source code separately if I want to change the TikZ pictures later.
4. If I want to update the picture, I have to go through this process again

Describe the solution you'd like
I want to be able to create TikZ pictures from within draw.io, similar to LaTeX & MathJax.

Describe alternatives you've considered
My current best solution is to use the online TikZ editor and download an SVG to import into draw.io. In draw.io, I put the source code next to the image so that I can change it later.

The issue names no files, tests, or entry points. Start by reviewing draw.io’s existing LaTeX and MathJax support, then compare it with the linked online TikZ editor workflow. Done would mean authoring TikZ within draw.io, rendering it for use in diagrams, and retaining editable source without a separate program.
