How to setup idle alert reminder on your Amazfit GTR

Sitting for long hours in front of the computer can cause back pain, neck pain, and other physical problems. So it is important to make sure that you take regular breaks to avoid these problems.
The best way to do this is by setting up idle alert notifications. These notifications will remind you when you have been inactive for a certain time period.
Setting up idle alerts is an easy way of reminding oneself to get up and move around every so often. A sedentary reminder can be set up on a device such as a phone or laptop.
