VERO app - how to set username & create account?

Here is VERO social network and I'm trying to set up username, and unfortunately it's not available. I'm just trying to get my first name username.

This action is final and you'll be unable to change this later, so I'm just showing you this step just so you know how to change your username. It's only possible to do when you're creating your account.

If you've chosen a wrong username here, that's it. It's not possible to change it. Maybe you can reach out to their support.

So anyhow. Yep, that is set up. Now my profile is vero.co/andriig. Then I have some featured content. There you have it. Now I created my account.
