Clarification on validating JWT using generated JWKS on apigee

[aramkrishna]

@DinoChiesa

We have followed this git project to generate the JWKS on apigee & we are able to generate JWT using listed curl command

curl -i -X POST -H content-type:application/x-www-form-urlencoded
-u ${client_id}:${client_secret}
-d 'grant_type=client_credentials' -d 'alg=rsa'
"$endpoint/jwt-with-jwks/oauth2-cc/token"

We are able to validate using validateToken.js from terminal, however for our use case if we have to validate JWT on apigee project itself rather than having external js file.
Do we have any ways to get the required public key using one of listed approach for validation ?
