I need help with the EssentialsX plugin

EssentialsX plugin:

I need help with the EssentialsX plugin. I transferred all the plugin files to the server (the library too) and the plugin is not on the server. I have the same problem with permissions because I don’t know what code they have. Please answer quickly.

It looks like that plugin includes a link to its documentation / has documentation available on its GitHub repository. Have you read through it already?

yes, but there is nothing about permissions
