Hello Jeremy Beynon,
Welcome to the MS Q&A Forum.
You have the option to either create a new user in your Entra Id (Azure AD) or invite a guest user and provide access by using the existing roles, or you can create custom roles that best fit your team's needs.
Kindly review below tutorials:
- Create a new user
- Add guest users to the directory
- Grant a user access to Azure resources using the Azure portal
- Create or update Azure custom roles using the Azure portal
Hope above will help you to finish the set up.
Sincerely,
Olga Os.
