Not a standard port in Rocket.Chat Desktop App

Hi. Can I specify a port other than 80 or 443 in the application Rocket.Chat Desktop App? For example 4443.
Tnx.

I will add. The new version 3.0.2 of Rocket.Chat Desktop App cannot connect to the server address https://rocket.example.com:9443. Rocket.Chat Desktop App version 2.17.11 works fine with this server address, just like the browser.
