Used the warpcast frame validator https://warpcast.com/~/developers to display the frame and confirmed button redirected to invite link provided as the parameter with the following url in the warpcast frame validator: https://<keyserver url>/https%3A%2F%2Fcomm.app%2Finvite%2Fcryptoleft
Used a different link than a Comm link and confirmed it still defaults to `https://comm.app`
