Keyboard extension returns to WhatsApp Business instead of WhatsApp after recording

I have both WhatsApp and WhatsApp Business installed on my iPhone. When I use the Monologue keyboard to dictate inside WhatsApp (personal), the extension opens the Monologue app to record, but when it returns focus it lands on WhatsApp Business instead of the personal WhatsApp I was typing in.

Steps to reproduce:

1. Install both WhatsApp and WhatsApp Business on iPhone

2. Open personal WhatsApp, start a message

3. Tap the Monologue button in the keyboard

4. Complete dictation

5. Focus returns to WhatsApp Business, not WhatsApp

Expected: returns to the originating app (personal WhatsApp) Actual: returns to WhatsApp Business

Guess is iOS is resolving the whatsapp:// URL scheme to Business as the default when both are installed, but you may have more visibility into how the return-focus mechanism works.
