What does disable_notification do in pinChatMessage?

[nmlorg]

I usually keep group chats permanently muted, so I'm not really familiar with disable_notification in general, but I'm experimenting a bit and am getting a little confused. When I do …, Android Telegram/Telegram X pops up a notification of type …:

call	Telegram	Telegram X
sendMessage(chat_id=C, text=T)	Groups/Default	Groups
sendMessage(chat_id=C, text=T, disable_notification=False)	Groups/Default	Groups
sendMessage(chat_id=C, text=T, disable_notification=True)	Other/Silent	Groups 🔕
pinChatMessage(chat_id=C, message_id=M)	Other/Silent	Groups 🔕
pinChatMessage(chat_id=C, message_id=M+1, disable_notification=False)	Other/Silent	Groups 🔕
pinChatMessage(chat_id=C, message_id=M+2, disable_notification=True)	Other/Silent	Groups 🔕

(C is the id of a type=supergroup chat that does not have an @-username.)

I might have messed something up with my clients' notification settings years ago without remembering, I guess I'm just wondering if this is what's supposed to happen and I'm just misunderstanding the intent.

When regular messages are sent disable_notification means that notification will be shown without sound for those who should receive the notification.

When a message is pinned without disable_notification all chat members will be notified. But the notification of all members isn't allowed too often, and all subsequent pins will behave as if they are sent with disable_notification == true for some time.
