How to cache all members? Discord.Js

Question

When i run the code below it gives only 1 member which is the bot it self. (in my test server with the bot and me.) Is there a way to refresh/update the members cache?

console.log(MainGuild.members.cache)

MainGuild.members.fetch().then((members) => {
 console.log(members);
 // code...
});
