How to maximise the console screen of noVNC (Console) option

[jjk.saji]

Dear All,
Good morning
I am using ProxMox 6.3-3 VM
I am able to create machine and see the display screen using he Console option, but the display option is fixed, I drag the borders of the screen to make it larger, what ever I do it resize it back to the default one.
request guidance or reference to a doc or url where I can find out to maximize the console screen
