Frontend update of a development powerpoint add-in that is managed through the admin center

Question

Hello,

I have developed a powerpoint add-in and it is managed through the admin center. The add-in is distributed to all members of our organisation.
It is a deployed static website (deployed in Google Cloud Platform (GCP)) that calls an API that is also deployed on GCP.

The Add-In is distributed through the link to the manifest.xml which is stored at GCP. I want to update an API call of my backend that comes from the frontend. I want to send another variable. The issue is that when I adapt my frontend and backend in the cloud the backend changes are (of course) immediately adapted but the changes in my frontend are not updated. So the calls fail. Changes in the static website are not updated automatically. Is there a way to trigger that the add in loads the files from the cloud again?

I already tried to clear the web cache but that did not help.

Thank you for your help!

-Johannes

Outlook add-ins can take up to 24 hours to appear on app. See Deploy add-ins in the Microsoft 365 admin center for more information on that.

Also you may pay attention to the Cache-Control headers that holds directives (instructions) that control caching in browsers. So, you could set up internet headers on the files stored on the server to let browsers know how frequent they should be requested from the server.
