As discussed, we want to count events when users opt to Vanish their account - the datasets we are saving to do not record username, just anonymized events. We also won't be counting success or fail, just the singular click on the Vanish Account option.

For iOS:
action = vanish_account Note: This should be recorded when user clicks 'Continue' on warning screen, not initial 'Vanish Account' click
category = setting (if applicable)
Schema:
event.ios_login_action

For Android:
action = vanish_account
source = settings (if applicable)

Schema:
event.android_create_account_interaction
