Hub can't be opened from Editors (versions 2022 and 2023):

When Hub is not running and user makes an IPC call (log in, open project, manage license etc.)  then "Install Unity Hub" window opens.

Details: Hub actually starts, i.e. it receives {{{}health:check{}}}, {{{}config:get{}}}, {{{}connectedInfo:get{}}}, {{userInfo:get}} , {{orgInfo:get}} events, but the one that triggers showing the Hub window ({{{}window:show{}}}) is not received.
