Zoom Phone App - phone interface - ADD Speakerphone button

Feature Request - ADD Speakerphone button to the Zoom Phone App / phone Interface (TOP)

There are times when I am on a phone call (using my headset) and I would like to press a (Speakerphone) button that would change the Audio to Speakers & Microphone.

Sometimes I have other people around my desk-area and they would like to contribute to the phone call. If there were an “easy-button” to switch the Audio from Headset to Speaker/Microphone - this would be a helpful feature
