!knife command for priority players

[Naepa]

Hello, guys
Sorry, if i make this thread on wrong part

So, i have a public server that installed CSGO Dedicated Server. Also, i have installed Knife plugin there. So, we can use command "!knife" (without quotes) to change our knife.
The problem is how to give permission "!knife" to some players (priority) ?
Example, Player A donate $1 to me, i will give permission to him to use "!knife" command. At the same time, Player B is just visitor, he can't use "!knife" command.

Thank you, guys. I hope you can help me...

ask the people who developed the plugin for faster answer. People here might be familiar with csgo server and its plugin but this is the wrong forum
