"Will you be away?" - dismissable for 24hrs

I’m on Safari browser, on Mac.

The “Will you be away?" message comes up on every page view.
I have to dismiss it, on every page view. to read important information on the page - eg. the project title.
See this screen grab ….

Once I have dismissed the “Will you be away?”, keep it off my screen for 24 hours.
