Call Method From Another Plugin

Hello! Please help me properly call the method of another plugin, it has PlayerInfo, and within it another Find, I tried to call how so, but nothing happened, please tell me how to do it right can?

[PluginReference] Plugin XDStatistics;


XDStatistics.PlayerInfo userstat = XDStatistics.PlayerInfo?.Call("Find", player.userID);
System.Console.WriteLine(userstat);

In the plugin itself this method is called like this

PlayerInfo Player = PlayerInfo.Find(player.userID);
(string)RustTranslationAPI.Call("GetItemTranslationByShortName", language, shortname)​

This is how I use it, maybe you can refer to it?
