- After 4 seconds, prompted to sign in with TikTok
- After auth, redirected back to promo page with videos loaded
- User selects a video
- Video data stored in sessionStorage
- User redirected to campaign wizard starting at step 2
- Wizard shows selected video at top of step 2
- User can continue with campaign creation
