I am having difficulty for oauth2 CLIENT_ID.
1. the quick start https://developers.refinitiv.com/en/api-catalog/refinitiv-data-platform/refinitiv-data-platform-apis/quick-start says CLIENT_ID can be generated as API key by myself
2. the user guide https://developers.refinitiv.com/en/api-catalog/refinitiv-data-platform/refinitiv-data-platform-apis/documentation#news-user-guide says CLIENT_ID will be provided to me by ThomsonReuters
3. I tried to generated one myself following the quick start but it did not work
can someone clarify?
