• [x] incorrect flow behavior actual: on click:
• user is redirected to the relevant activity page
• activity notification is removed (as if the user clicked the x to delete it)

expected: on click:

• user is redirected to the relevant activity page
• activity notification to stay visible in the notification menu
• notification menu to close and show the relevant activity page (which was opened on step 1)

• [x] menu flow update flow:
• click the bell icon
• click "view activity" on one of the existing notifications actual:
• redirect to the page AND menu stays open. this result in not knowing that the redirect happened. expected:
• redirect to the page AND CLOSE the menu.
