Using Sidecar While Connecting to an External Display

Is it possible to use Sidecar (in Extended Mode) while connecting an External display thus having three screens?

Sample Scenario: I connected an External Display using the USB C to HDMI adapter and set it to Extend Mode... I then connected my iPad (Sidecar device) through USB to my MacBook Pro and setting it to Extend Mode as well. Having a total of three displays.
