Feature request to add custom ports in the rawURL syntax for RocketChat

[atighineanu]

By default, send is using the formatted hook, like this "https://%s/hooks/%s/%s", host, tokenA, tokenB. However, in cases when my 443 port is busy with a different service, and I've set the chat service to use port 5000 or 3000, adding the port into the rawURL - it ends up with an error.

It would be a nice feature to have.
