The procedure for linking the admin panel is as follows:
① From the [Invitation Linking] section of the admin panel, enter the email address of the user of the app you want to link and send an invitation email. (Unregistered email addresses are also acceptable.)

② Connect with your team via the URL provided in the invitation email. If you already have an app account, enter your app account information. If you don't have an app account yet, create one.
If you register your account via the URL in the email, you will not need to register a credit card.
