Per feedback from the community, logging this for tracking purposes. This functionality is present in the Java client.

and also referenced in Doc

We are also writing JWTManager implementations into each of our client libraries so you don’t have to write those yourself. At the time of this writing, the Java and Node clients both have a JWTManager you can use. The other languages might have a JWTManager implementation now but if they don’t, just submit a support ticket or a Github issue and we will write one for you.
also, is this still true.  I searched for JWT and manager and could not find this in the typescript or java client. If the JWTManager development is deprecated, I can remove this bit from the article.
