The new setting are relatively simple to use.
To have basic connectivity all you have to do is put in your channel name and connect, this'll allow you to use the debug menu which'll help set up how you connect to twitch.
When the twitch debug is enabled then any time a message contains a redeem you'll get a very long string copied to your clipboard.
Find the part that says custom redeem ID and paste that string of letters and numbers into the redeem option in the settings menu that correlates with which redeem you used. (For now the redeems need to have a message connected with them so make sure to enable that)
After this any time someone redeems the linked node the program will read that when connected and automatically use whatever redeem it correlates with.
