I am using the mermain app within Miro to import mermaid entity relationship diagrams into Miro. If you have a large mermaid ERD, you get a maximum text size error. In Mermaid live you simply edit the config file and add the line   "maxTextSize": 90000

Miro gets the same error with large diagrams, is there a way to edit the miro/mermaid config in the same way ?
