Missing a TrayToolTip Display Duration

[BourgeoisDirk]

I'm missing a way to set how long a TrayToolTip will stay open using a Duration.
Now it only shows up while hovering over the trayicon, i would want it to linger for a couple of seconds before it fades away.
Not finding any options or ways to do so ?

Even when keeping the mouse over the trayicon, the traytooltip will go away after a while.
I would like the option to keep it open while mouse is over trayicon, and a duration for it to stay open after the mouse leaves the trayicon, and then fade away
