Navigate to Login Details and then select the streaming platform you want to connect with. Click both of the platform login buttons (Note: (#3) is for your "Bot" account, which is the account that will be typing responses into your chat room)
The bot account can also be the same as your primary channel login if you want.
After you connect the platforms you should be able to click the "Test" button (#4) to make sure the connections are working. A green checkmark will appear if the logins are connected properly.
Allowing multiple platforms
Click the box for "Allow multiple platforms" and then click "Add this platform". You can do this for multiple streaming platforms in the dropdown selector.
Each platform has it's own associated color when you add it to the list of streaming services you will connect with. You can see which ones are added by looking beside the connect button for multiple colored boxes.
purple = twitch, yellow = dlive, red = youtube, dark blue = facebook, light blue = glimesh ...
