I got this issue when trying to get access token. So I don’t know how to get code challenge and its method. I tried to search around them but nothing is suitable for my issue. It also tell me bout CODE_VERIFIER, and I’m stucking with how to get these values and solve my problem. Can anyone help me to resolve this issue?

"error": "invalid_request",
"error_description": "code challenge and code challenge method required"
}
