Answer 1

Inject \Magento\JwtUserToken\Model\Reader and then call read($token) on it.

In PHP8.1 this looks like

public funtion __construct(private \Magento\JwtUserToken\Model\Reader $jwtReader) {
  
}

public function test() {
    $context = $this->jwtReader->read($token);
    $userId = $context->getUserContext()->getUserId();
}
