Hello Ruthless22, apologies for the late reply - I did not see your review until now. Thank you for reviewing the plugin. You can use a permission plugin like LuckPerms or any other permission plugin to give players permissions to throw ceggs. The permission to throw ceggs is: tce.throw
If you require further assistance, don't hesitate to send me a message anytime.
Edit:
I have updated the plugin to 2.3.0 which includes a new configuration line under the "options" section in the config.yml where you can disable the need for a permission to be assigned to players to throw ceggs, please see:
