Aspire integration test with a protected api(via AddMicrosoftIdentityWebApi) failing

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

I have a protected api (using AddMicrosoftIdentityWebApi), when testing it via aspire integration test, the request to the protected resource returns 401, even if the access token attached to the header is valid.

On a non-aspire integration test, the same test works as expected.

### Expected Behavior

Should be able to access the protected resource with a valid access token.
