This is partially working due to changes in the Riot API, it looks like they’ve noticed the problem and are trying to fix it. It still works, but it's slower. I am working to try new ways.
If the app isn't kicking the user from room immediately after inviting, maybe it's a rate limit of the API, as I said above. Be caution using this bcoz this is considered a crime depending on the country where u live. Denial-of-service is a crime and I am not responsible for your actions.
