[Question]: checking token validity before sending HTTP requests

[Stalaktite]

What Version of the library are you using?
I'm using version 15.0.3 with silent renew

Question
Hello,
On my Angular frontend app I have silent renew working properly with a third party auth server, and tokens are correctly added to my HTTP headers for backend queries thanks to the HTTP interecptor included with the library.

The only problem I get is after a long browser inactivity (for example, computer in sleep mode for an hour) when the Angular app wakes up it sends queries to the backend to update the data, using an expired token, while - in parallel - the silent renew is being called.
As a result, I get error messages from my backend for a very short period of time and I have to ignore them and/or find a way to replay the query by catching 401 HTTP errors.

Is there any option to force the HTTP interceptor to check the token validity before each call, and delay the queries if it is invalid?
Alternatively, what would be the best approach to check for token validity, say for example in another chained interceptor, to manually delay any queries while the token is being refreshed?

Thanks for your help,
Antoine
