### Add/Invite/Remove someone in a chat
```csharp
using var client = new WTelegram.Client(Environment.GetEnvironmentVariable);
await client.LoginUserIfNeeded();
var chats = await client.Messages_GetAllChats(null);
const long chatId = 1234567890; // the target chat
var chat = chats.chats[chatId];
```
After the above code, once you have obtained an InputUser (or User), you can:
```csharp
// • Directly add the user to a simple Chat:
await client.Messages_AddChatUser(1234567890, inputUser, int.MaxValue);
// • Directly add the user to a Channel/group:
await client.Channels_InviteToChannel((Channel)chat, new[] { inputUser });
// You may get exception USER_PRIVACY_RESTRICTED if the user has denied the right to be added to a chat
// or exception USER_NOT_MUTUAL_CONTACT if the user left the chat previously and you want to add him again
// • Obtain the main invite link for a simple Chat:
var mcf = await client.Messages_GetFullChat(1234567890);
// • Obtain the main invite link for a Channel/group:
var mcf = await client.Channels_GetFullChannel((Channel)chat);
// extract the invite link and send it to the user:
var invite = (ChatInviteExported)mcf.full_chat.ExportedInvite;
await client.SendMessageAsync(inputUser, "Join our group with this link: " + invite.link);
// • Create a new invite link for the chat/channel, and send it to the user
var invite = (ChatInviteExported)await client.Messages_ExportChatInvite(chat, title: "MyLink");
await client.SendMessageAsync(inputUser, "Join our group with this link: " + invite.link);
// • Revoke then delete that invite link (when you no longer need it)
await client.Messages_EditExportedChatInvite(chat, invite.link, revoked: true);
await client.Messages_DeleteExportedChatInvite(chat, invite.link);
// • Remove the user from a simple Chat:
await client.Messages_DeleteChatUser(1234567890, inputUser);
// • Remove the user from a Channel/group:
await client.Channels_EditBanned((Channel)chat, inputUser, new ChatBannedRights { flags = ChatBannedRights.Flags.view_messages });
```

Instead, if you want to deal with multiple users from the same machine, the recommended solution is to have a different session file for each user. This can be done by having your Config callback reply with a different filename (or folder) for "**session_pathname**" for each user.
This way, you can keep separate session files (each with their authentication keys) for each user.
If you need to manage these user accounts in parallel, you can create multiple instances of WTelegram.Client, and give them a Config callback that will select a different session file.
If you need to manage these user accounts in parallel, you can create multiple instances of WTelegram.Client,
and give them a Config callback that will select a different session file ;
for example: `new WTelegram.Client(what => Config(what, "session42"))`
Also please note that the session files are encrypted with your api_hash, so if you change it, the existing session files can't be read anymore.
Your api_id/api_hash represents your application, and shouldn't change with each user account the application will manage.
