How to activate the unique domain name

Hi Bubble forum community. I’m a total newbie in terms of app and web development. I’m an entrepreneur - a struggling one - who is a solo act, financially broke. Therefore, I have no choice but to DIY my way through this program. I don’t know if I’m mistaken - if I am, then I stand to be corrected - but, I think I saw, somewhere in my email correspondence and/or onboarding, that with the team plan, I can register a unique domain name for my app: Phantanetwork. Is this possible, and if it is, how do I go about doing it?

Adding custom domain is possible on any paid plan (from 29$/32$ per month).
And for discovering the process of adding custom domain - check official manual.
