What is the standard practice to accompany guests in and out of the elevator, if it is an unmanned elevator?

The host opens the elevator door for the guest, then blocks the elevator door with one hand (arms and fingers should be raised straight and fingers should be put together) and says, "Please!" Wait for the guests to go in, then go in and press the floor you want to go to;

After arriving at the destination, the host still blocked the elevator door with one hand (arms and fingers should be straight and fingers should be close together) and said, "Please!" Don't go out until all the guests get out of the elevator.

Note: No matter leading the way or getting in and out of the elevator, the owner should walk in front of the guests (whether one person or many people) and communicate with the guests properly!
