GtaV Xbox one online change name?

Have read that you can change the name the other player can see online, the gamertag so to speak. Is that correct? Is the gamertag the name the others can read? It also costs 9.99 euro

Underneath stood also that you have to inform the friends about the new name net because the friends list is automatically updated.

It comes

That means what now?

Right,

Gamertag is the name that you can see for others.

Among other things, there's still a character name but only for you and no money costs.

Thank you;)
