Issue description

In the SPFX it's possible to make HTTP requests to Azure using AadHttpClient.post / get.

But sometimes it fails to get the access token inside of these post / get methods with error "Error: Token request previously failed".

To avoid this I currently getting token (from context.aadTokenProviderFactory.getTokenProvider() + then getToken => which returns the token string) and make the usual JS fetch request with this token.

Getting token is secured with the retry and w/o cache to avoid the error above.

Obviously I try to avoid send connection string or other credentials to the frontend except of the Entra ID token.

Questions:

1. Is there a way to use AadHttpClient.post / get but with possibility to request a new token if "Error: Token request previously failed" ?
2. Since it's used for Service Bus ideally would be using their native library, but during the tests seems it's impossible to implement TokenCredential with SPFX AAD Token, maybe because it lacks other props from accesstoken, is there a way in SPFX getting these? (nuances if service bus lib is working at all in the browser is another topic, rather not) Preferrably in a form of TokenCredential, but not nesessarily.
