I accidentally delete the Billing account administrator role. How can i restore it?
1. Go to IAM & Admin > IAM.
2. Choose the member you want to add the role to and select Edit for that member.
3. In the Edit Permissions dialog, click Add Another Role.
4. Enter "Billing" as the filter and select the desired role.
5. Click Save and you’re done!
Thank you so much. I did this, too.
