We need to use Zoom in our Board Room

It is not possible to have 10 member is the board room to share the mic from a single laptop.

While there are products meant for bigger rooms like the Logitech https://www.logitech.com/en-sg/video-collaboration.html available for purchase, there are existing equipment that your office may already have.
Most offices in NUS will have the the Polycom Trio used for boardroom telephone calls. That Polycom Trio can also be connected to a laptop; either Bluetooth or USB.

USB
Use a Micro USB cable to connect the Polycom Trio with the laptop.
Select the Polycom's Speaker and Microphone device in Zoom.
Run the Test Speaker and Microphone to configure it.
