Discord notifications do not accumulate in Notification Center when MacBook is in sleep mode

There is no problem with my settings, so there is no need to reinstall the program or change ㅡmy settings.
For all MacBook users, Discord notifications do not accumulate in the notification window when the MacBook is in sleep mode. (but Telegram, Mail, etc. all work well)
This is a Discord bug, and as a result of inquiring to the Apple service center or to all acquaintances who use Discord, it was confirmed that it is a 'Discord bug'. Therefore, I propose to fix this bug where notifications are not accumulated in the notification center when in sleep mode.
