How can I call a team creation and associate the team with the user after successfully logging in and having data in the database?

I am currently working on creating a team associated with a new user using the signIn method provided by auth after logging in. However, my database does not have user data after unsuccessful login, so I am unable to associate the created team with the user

async signIn() {
    ....
      return true
},

How can I call a team creation and associate the team with the user after successfully logging in and having data in the database?

To be precise, I lack a callback after successful login, rather than a callback during login.
