Manifest 3 add-on bugs

Question

almost a week ago I started to make an add-on that I finally understood how it works (yes, because before I had never made an add-on ^^) and I managed to make it work under Manifest 2 but when I wanted to publish it on the Google Web Store I had the surprise that the add-on must be in Manifest 3 while Mozilla and Opera had accepted the 2. But no matter, I've been looking for a little bit how to migrate it to V3 and I found some interesting things but not really what I was looking for to fix my bugs that changed during the migration.

I have to explain you what is an add-on so that we can find a solution together. It's an add-on to alert people when a streamer is live. And what blocks it is the offline visual part which is still in Live while the streamer is offline. I think it's the local storage that blocks but I'm not sure because of the number of bugs I had. But what I am sure of is that the worker service is marked as Inactiv. I put a little bit of my codes in hope that someone who knows well the Manifest 3 can help me. And I'm willing to send the whole code if people need it.
