From openid-configuration to user JWT information by curl

I am looking for user's information full steps from OpenID configuration to user information by curl in Keycloak.

I can get openid-configuration API via curl

curl --location --request GET 'http://localhost:8080/auth/realms/my-realm/.well-known/openid-configuration'

I got this result but have no idea what is next step. Can you someone help me how to get a JWT token and get a user information by curl commend?

Here is step for get user information from get openid-configuration

1 get access token URL

TOKEN_URL=$(curl --location --request GET 'http://localhost:8180/auth/realms/test/.well-known/openid-configuration' | jq -r '.token_endpoint')
echo $TOKEN_URL

result

http://localhost:8180/auth/realms/test/protocol/openid-connect/token

2 get ID token form #1

ID_TOKEN=$(curl --location --request POST "$TOKEN_URL" \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id=admin-cli' \
--data-urlencode 'grant_type=password' \
--data-urlencode 'scope=openid' \
--data-urlencode 'username=user' \
--data-urlencode 'password=1234' | jq -r '.id_token')

echo $ID_TOKEN

result

3 decode ID token

jwtd() {

         jq -R 'split(".") | .[0],.[1] | @base64d | fromjson' <<< "${1}"
         echo "Signature: $(echo "${1}" | awk -F'.' '{print $3}')"
    fi
}

jwtd $ID_TOKEN
