Activity objects are Notifications or Activity feed items

for each of the following, only show activity feed items where hasAccess=true i.e. never show for private pages, only show for shared and public

• User started following Page
• User started supporting Page at $0.24 / month
• User submitted changes to Page - show Diff view
• User approved edits to Page click to see what changed! - show Diff view
• User requested to join your community - Request to join community
• User joined community (which you're a member of)
• the 72 hours is over! Page is now unlocked! - Time unlock

all of these need to show a timestamp too, in relative format, upon click it’ll show absolute time
