Deploy sanity studio to direct vercel without localhost

[egorov-maxim]

Hello,
Can some one point me to answer how to solve this problem?
Instructions, videos, links, any source. I could't find answer.

I tried to copy this repository https://github.com/sanity-io/sanity/, and deploy it to vercel.
But it stops deploying on this moment and stays there:

13:50:56.905 | You can also set up best practice Sanity projects with
13:50:56.905 | your favorite frontends on https://www.sanity.io/templates
13:50:56.905 |  
13:50:56.906 | We can't find any auth credentials in your Sanity config
13:50:56.906 | - log in or create a new account
13:50:56.908 | - Fetching providers...
13:50:57.117 | ? Login type (Use arrow keys)
13:50:57.117 | ❯ Google
13:50:57.117 | GitHub

I see that it says, «can't find any auth credentials in your Sanity config». I was trying to find the config file, but it's not there.
I belive it is easy question, but I have no tech background and its kind of pain for me.
Can you please, point me how to solve it? Or may there is an easy solution?
