[Feature Request] Add "Mark as read" to tray-menu

[BeeJay28]

I often get messages while working, I see the notifications pop up, read the message and decide I do not want/need to reply to that. I would like to be able to right-click on the tray-icon and select something like "mark all as read".

I haven't look deep into the code, since I never really worked with electron, but maybe WhatsApp offers some API or something, that you can access with the login data from the browser-client login?
