Web Browser: Hide Tabs

[Bloodsong 13T]

i'm trying to make the overlay web browser take up less space. is there a way to hide the row of tabs when i only have one tab open? or is there a way to make one web page take up the entire browser?

trying to use discord for BG3 in-game text chat (since they neglected to put one in). but discord is so honking huge, and it's blocking a big chunk of the screen. :/
