Charge through use of an adapter....

Two Things:

Q1. "I use wireless mouse to work on it so I have to connect the multipart or while connecting to the projector while presentation."

A1. No Bluetooth Dongle Needed:

Bluetooth should be built right in to your Mac. So, the dongle would not be needed.

Confirm the Mouse's Connection:

First off, see if the camera is even seen: 

1. Hold Down: the Option key
2. Click: the Apple menu
3. Choose: System Information or System Report
4. Select: Bluetooth from the list on the left
5. Look For: any internal or external mouse:

Q2. "At that time charging port is also occupied by this multi functional device."

A2. Use this Adapter: USB-C Digital AV Multiport Adapter - Apple Support

The HDMI cable would go from the projector, right into the HDMI port of the adapter, whereas the power adapter for the charge would go right into the USB-C port. I use it every time I'm watching something on my projector.
