Same early plant + custom Start Chat as Custom Launch.
After SDK init we call hidePreSurvey and openEntrypoint to skip the
pre-chat form and open a fixed UserHub entry point.
Phase 3 calls these immediately after guide.init — chat opens on this entry point
without the precontact survey.
Use the floating NICE Guide button (bottom-right) or our custom button below.
Both should open the same chat instance — custom path programmatically clicks the
native GUIDE_CHANNEL_BUTTON bubble (same trigger as the floating widget).
Copy this link and open it anywhere (another browser, phone, email, SMS).
It carries ?wowVid + ?wowThread (+ window/customer ids when known).
The destination page runs early plant before NICE loads — same as nav buttons.
What happened before the NICE SDK loaded. Also logged to console as [EarlyPlant].
Append ?wowVid=&wowThread=… when hopping between azure0x.{tld} hosts.
Same param bundle — early plant on the destination is the only cross-TLD bridge.
Planting ON: nav or paste resume URL → thread reconnects.
Planting OFF: same link → new session (proves early plant is required).
