Editing the OpenType MATH table

I’ve recently started tinkering with fonts for mathematics in Glyphs. OpenType features such as ssty and dtls seem to work perfectly. However, I can’t figure out how to edit the OpenType MATH table in Glyphs. I know that this is a pretty niche feature, but is there a way I can access it via custom parameters or scripting?

FontForge has a UI for editing this table, but I’d love to keep a pure Glyphs workflow.

Any tips would be greatly appreciated!

I have worked on some parts of the math workflow but didn’t finish it.

FYI, I created a plugin for editing MATH table and it is available from the plugin msnager (Glyphs 3 -only),
