How to define a rate limiting policy for Duende IdentityServer endpoints?

[merijndejonge]

Which version of Duende IdentityServer are you using?
7.0.8+f28cac9
Which version of .NET are you using?
8.0.10

I'm trying to rate limit the different endpoints of Duende Identity Server using the Microsoft.AspNetCore.RateLimiting middleware.
According to the docs (https://learn.microsoft.com/en-us/aspnet/core/performance/rate-limit?view=aspnetcore-8.0 and https://blog.maartenballiauw.be/post/2022/09/26/aspnet-core-rate-limiting-middleware.html) there are two ways to add rate limiting: by setting a rate limit globally, or by setting rate limits by policies.

Using the global approach works as a charm, but I want to have more fine-grained control over rate limits in different parts of my system. Therefore, I prefer rate limit policies over global rate limits.

However, I have now idea how to get such policies applied to the default endpoints of Duende IdentityServer.

Any recommendation?
