I need help! How do I dynamically change lexical highlighting ::>_<::

[HBolck]

My requirement is that the monaco object is already created, and as the business scenario changes, some new keywords are added in real time and highlighted.

I found something in this, but I'm not sure it'll solve my problem.

You might be able to do something clever with semantic tokens.
