You can set your home page to be a microflow. If you go to the project module > navigation you can see a setting called “default home page”. When you press select you can select a microflow or choose to create one.
Another option would be to use the role based home pages. You can assign certain home pages for a specific user role.
Hope this helps!
There is an appstore widget called MicroflowTimer. It should have this feature.
You could also add a dataview to your page and use microflow as datasource. In this microflow you can do whatever you want. But you need to return an object (but it can be a dummy object). It’s a little bit dirty, but it would work.
