From the Navigation choose a Microflow as the Default home page.
if you want to trigger for specific user roles use Role-based home pages.
Hope this will help.
Make a microflow where you do your stuff and use that microflow in your navigation as the Default home page. Do not forget to open the correct page at the end of this microflow. This way this microflow is always triggered and it will still open up the page you want.
below is the microflow which i am trying to fix. any ideas how to paste the full image…
