Setup custom plugin that colors text based on regex match

[samballa07]

Hello, I have a use case that I think will require a custom plugin, but am having trouble setting it up.
I need the editor to dynamically change text color depending on if it matches a regex and only the text that matches the regex should be colored. It seems the Lexical dom is wiping out any html modifications I make to the editor html. To be clear, this is purely for user visualization as they edit content in the editor and i dont need custom markdown for colors. Could someone help point me in the right direction to get this solution
