n!kick command only require one argument, just the mention:
@Clyde. You can also put a user ID instead of its mention.
n!tempmute requires a duration. For example, you will need to run
n!tempmute <@user> 1d [reason]
For durations you can use and combine minutes, hours, days or weeks: 1d45m will mute/ban for 1 day and 45 minutes.
For each command you can add a reason as the last argument. If you do not give a reason, the bot will set it as N/A or No reason provided.
Make sure Nate Bot has permissions on the role in your server settings, you can find out how to configure them here.
Make sure you add an allowed role to the command in the edit page, so your moderators can use the commands.
