For Helix Subscriber Count

I just want to take the data of my own channel and publish it on my website.It shouldn’t be this hard! Why am I still having problems even though I have given the necessary permissions through the console. It’s so silly.

https://id.twitch.tv/oauth2/authorize?client_id=(ClientID)&redirect_uri=(MyWebSite)&response_type=code&force_verify=false&state=D1f3%2BNV1N2vlnw%3D%3D&scope=
I have authorized via this link. And the authorization I have given in the Account Settings - Connections section of my channel is visible.
