In my desk, how to add a waypoint with its coordinates in offline mode?
Thank you

This is not an option right now. But maybe DJI can add something like this in the app, or create a web-based app for consumer drones to do this and more, even with monthly payment.

Thank you for your feedback. I will take this as a suggestion of yours and will forward it to our designated team for attention. After the evaluation of the engineers, significant suggestions or requests will be implemented via the firmware update, app update, etc. For any updates, please stay tuned to the latest news on our DJI official website at www.dji.com. Thank you for your valued support!
