My bot has a live OAuth WhatsApp connection (one production number, ~1 year of customer conversations, cannot be disconnected). I want to ADD my existing WhatsApp Business app number via Meta Coexistence.
I've verified your "Connect with OAuth" launches Embedded Signup with featureType: whatsapp_business_app_onboarding — great. But on a bot that already has a connection, that button does nothing (no popup, no network request).
Question: if I onboard the second number into the SAME WhatsApp Business Account the existing connection already uses, will the integration see both numbers (e.g. after hitting the refresh icon on the connection)? The config has a "Default Bot Phone Number ID" field, which suggests multi-number support. Does inbound from both numbers route to the bot?
If not, what's the recommended way to add a second number without disconnecting the first? Thanks!
