Bring your own font in SharePoint? New Brand Center

Hi -

In this announcement one can read about "Introducing the new Brand Center in SharePoint"

SharePoint in the AI Era: Introducing Copilot in SharePoint & 10 more innovations for creators - Microsoft Community Hub

I would like to know if it will be possible to bring your own fonts or if it will be a selection of fonts to choose from? Also, I wonder when this will be rolled out. Thank you in advance!
