Hello @博和 田口
You could use Remote Desktop or Remote Assistance based on your practical scenario:
The difference between them are:
Remote Desktop allows you to use or “take over” a computer located elsewhere as if you were using its screen, keyboard, and mouse. It is designed to allow you to remotely control a computer as if you were sitting in front of it.
On the other hand, Remote Assistance is designed to allow one person to help another by accessing their computer, either to view or to control it, while the person being helped watches. It is commonly used for technical support purposes.
In summary, Remote Desktop is for unattended access while Remote Assistance is for remote collaboration.
