How to implement Custom Time LED Blinking in Blynk?

Hello all,
My mobile will automatically update the virtual pin value to 1 if an important text message comes to my mobile.

On my Nodemcu when the virtual pin is set to 1 it should do the following:
A LED should be ON for 10 mins and OFF for 5mins in a loop until the virtual pin becomes 0.

How do i do it in a clean way?
