I figured it out. Left joycon is the key.
Here are the steps:
1) Set date to July 11th. Go to Home Screen.
2) Place select cursor on News. (don't open it though)
3) Remove right joycon only. Press down direction on the control stick.
4) You will see indication on the screen to press the shoulder button on the left joycon. (Shows the button in GREEN. This is a Good sign!)
5) Press the shoulder button on the left joycon as you remove it from the Switch.
6) Lay the left joycon on the floor. (must be lower elevation than the Switch system)
7) Hold the right joycon in your hand, face the ir sensor towards the left joycon on the floor.
8) Hold the ZR shoulder button on the right joycon (keep the joycon facing the floor)
9) VERY IMPORTANT STEP
You must step on the left joystick and press the button (this is simulating the golfball on the tee)
10) With the left joystick button held down, rear back and take a swing.
11) You must release the left joystick button and right joycon ZR button at the same time, as your swing passes over the left joycon's position.
12) floG will launch
