> Hello, I was exploring the documentation at [https://marketplace.zoom.us/docs/guides/auth/oauth/#getting-an-access-token](https://marketplace.zoom.us/docs/guides/auth/oauth/#getting-an-access-token) and following the steps to get an OAuth application going. However, I wasn’t able to find the way to verify the signature of the token - what’s the key used to sign the JWT? I assume it’s a shared secret rather than a key pair (but if I’m wrong, is there a public key the Zoom publishes?) Thanks
