App Store Connect

I connected to App Store Connect with my private key with the curl command line that was specified in the Generating Tokens for API Request and now I want to understand how to process a JWT Payload token with the command line specified in the "Generating Tokens for API Request" and don't understand how to use the commands POST or DELETE, can you help or are you interested in forming a team to solve these process issues ?

Can you give me a example of a curl command line that includes the json data of the request in the command or how to process the JWT Payload.json with the command specified to process the command from Xcode not from the Terminal.app ?

Kindly
