From here, you can view the available bot categories. For example you can type +help kick to view the available commands in the kick streaming category.
Note: If you see an empty message from Sx Live with buttons, you've most likely turned off embeds in your Discord settings. From your Discord app, go to User Settings -> Text & Images and turn on Show embeds website preview info from links pasted into chat.
Type +help all to view a full list of commands or visit our commands page on our website.
Make sure to use the prefix + before each command!
