Is it possible to authorize sendbird user?

Hi there! I’m implementing chat app using Sendbird, I have a business like this:

As an Admin, I can see all the channels and the messages of the app even if I isn’t a member of the channels

As an member, I can only see my the channels and messages.

I’ve tried to call API to get all the channels but its response is snake_case and different from sdk channel, I’ve convert to camelCase and passed to GroupChannel but I got errors because It doesn’t the function implemented by sendbird sdk.

Is it possible to authorize sendbird user to get all the channels and message by sdk ?

Appreciate that!
