I have a question about the Ad Manager in Kodular

When I try to register to Ad Manager, Kodular only give errors. It does not say that your account is not eligible. I think this error means my account is not eligible. So will my account never be eligible for Ad Manager? Do I need to open a new account?

Can anyone help plzz

This is really confusing. Can you clear this up?

I clicked this

it gives this error
