Hide youtube location using Google API in 2023

I want to hide YouTube channel location for now as a new YouTuber. By mistake I select the location and now option for hide. I saw some video they use this URL:(https://developers.google.com/youtube/v3/docs/channels/update)

This code:

{"id": "YOUR_CHANNEL_ID","brandingSettings": {"channel": {"description": "This is a short description.","defaultLanguage": "en"    }  }}

but it show me this error:

This error may be due to using an insufficient credential type. Try using OAuth 2.0.

What should I do now? Is there any easy way to do it?

Please help me.
