Figgure out weater bot.getApi().getChatAdministrators(message->chat->id) is an administrator

[Beerlesklopfer]

Hello Community

to me there are two missing samples:

ONE:
InlineKeyboardButton::Ptr btn_joinGroup(new InlineKeyboardButton);
btn_joinGroup->text = "BlaBla";
btn_joinGroup->url = "https://t.me/BlaBlaBot?startgroup=settings";
btn_joinGroup->callbackData = "joinGroup";

This the one to join a grouo

How to figgure out wether the typing user is and admin an its ChatMember attributes

Any hints would be apreciated

getChatAdministrators(chatId) already returns only the owner and administrators. Compare each returned member user ID with the sender:

bool senderIsAdmin = false;
for (const auto& member : bot.getApi().getChatAdministrators(message->chat->id)) {
    std::visit(
        [&](const auto& admin) {
            if (admin && admin->user && message->from && admin->user->id == message->from->id) {
                senderIsAdmin = true;
            }
        },
        member->value);
}

The bot must be allowed to obtain the administrator list. If you need particular permissions, inspect the ChatMemberAdministrator alternative; the owner is represented by ChatMemberOwner and has all administrator privileges.

The URL https://t.me/BotName?startgroup=settings only opens the add-to-group flow. A URL button does not send callbackData; url and callbackData are mutually exclusive button actions.
