Run Balloon Tip asynchronously

At the beginning of the script, the system tests whether a restart is stored in the system. If this is the case, the user is shown a balloon tip that he must restart the computer and the script ends with exit code 1641.
Intune has a grace period of a few hours. Does anyone know how I can run “Show-BalloonTip” asynchronously so that the balloon tip remains displayed for longer?
