Unable to install or uninstall Revenuecat purchases Firestore Extension

I have been unable to install or uninstall the Revenuecat Purchases Firestore Extension. After trying to then uninstall, I have received the following error. Note that we have Google Cloud Associated with this project and so IAM permissions etc. There is nothing about this in the documentation and how Google Cloud IAM permissions might affect the Extension installation or uninstallation. My account has full Owner permissions, as well as Service Usage Admin, Firebase Admin, and Eventarc admin. This is the error:

I've replaced the help code and project name with the above error.
