Why don't I get channel updates?

[EhsanKey]

For example, if the user becomes a channel member, I can't see it in the users' object
what's the solution?

  const result = await client.invoke(
  
    new Api.channels.GetFullChannel({
      channel: "@TESTTTTBUT",

    })
  );
  
  console.log(result.users);

channels.GetFullChannel does not return the channel member list and is not updated when regular users join — result.users contains only the creator, admins, and technically required users, so detecting when a user subscribes to a channel this way is not possible.
