VBA macro run at end of session, not file

MicroStation 2023 - v23.0.1.44-MS2023 VBA

I am looking for information on how to run a VBA macro at the closing of the MicroStation session. I already have the code to run at the open/close of a dgn file. I cannot seem to find any information on this specific topic or maybe no one has tried, or it is not possible. Thank you in advance.
