SCIM bridge provisioning gives 500 Internal Server Error

Hi, I have recently upgraded from 1Password Teams to 1Password Business and today I started setting up the automated provisioning. I would like to have connected to EntraID, and, as we are primarily on the Microsoft 365 platform, I was happy to see that the Azure Kubernetes SCIM bridge option was offered. I followed the instructions and successfully set up the Kubernetes instance. I updated the DNS records, and now I can see the status page at https://scim.{ourdomainname}.com/app/status. (I masked it for privacy, but I don't use the curly brackets, of course - same goes for the rest of the explanation)
The manual described creating an Azure Enterprise application, and this is where I get stuck. Filling out the tenant URL https://scim.{ourdomainname}.com and the bearer token - exactly the same one as I successfully use to access the status page above - gives me an error message:

```
You appear to have entered invalid credentials. Please confirm you are using the correct information for an administrative account.

```

I am not sure how to proceed, as I would deduct this as something that has to do with the image I deployed to Kubernetes. Could it be that there's something wrong with that, or am I missing something?

Thanks in advance.
