Using wx.addPhoneCalendar requires the following prerequisites:

1. WeChat version support: wx.addPhoneCalendar is the API of the WeChat applet and can only be used in an environment where the WeChat version number is greater than or equal to 6.6.6.

2. User authorization: Adding a schedule to the calendar of the user's mobile phone requires user authorization. The user needs to click the authorization button in the mini program to perform the operation. Authorization buttons can be implemented through the <button open-type="openSetting"> component.

3. Legal domain name: Mini programs that use wx.addPhoneCalendar must configure legal domain names in the mini program management background, including the calling domain name of wx.addPhoneCalendar and the calendar service domain name. During the development phase, you can use the "Do not verify legal domain name, Web-view (business domain name), TLS version, and HTTPS certificate" option that comes with the developer tools for debugging.

Note: Due to user privacy and security issues, the mini program can only be added to the calendar selected by the user and cannot select a specific calendar. getTime() needs to divide by 1000
