How to Use Own JWT token?

I am using springboot and angular for my application.
SpringBoot is using JWT token for angular auth.
I want to integrate Grafana so Once user click on link in angular,it will automatically login with that user and redirect to relevant dashboard.
There is auth method called JWT Authentication(Configure JWT Authentication | Grafana documentation). Can I use this? if yes then How?
Is there any other possible way to achieve this?
