periodical pop-up / user confirmation

Hi guys,

we love Bravo and have made good progress with our app. However, we are running in one little problem. We somehow need to implement a pop-up that asks the user to confirm something. The problematic part is that the pop-up should not ask for confirmation every time the app starts (I think I could use the special intro screen for that) but it should pop-up periodically (e.g., once a month). 

My question is: Is there any way to schedule a pop-up message (or a special screen) that appears once a month after opening up the app? I  thought about triggering remote actions in the backend. We use Xano. But I am stuck on what could trigger a remote action. I also thought about conditional visibility and remote actions. But I am still stuck on how to implement this. What UI Element could I use and how could I arrange this? 

Thank you all in advance for your help!
