BLE UUID conversion

Hello everyone,

I am trying to connect a DA14580 microcontroller to send data to the Garmin Watch though an App. I am using the example/sample code from the NordicThingy. On that code, I am trying to put the UUID service and characteristics of my DA14580, but the UUID that I have is like this:

 'EDAAC62E-9910-1BAC-5241-D3BDA6932F2F'

And the one on the sample code looks like this: (0xEF6802009B354933L, 0xEF6802009B354933L)

Do you know how can I convert my UUID to make it look like this one above? Should I use a different line of code?

P.D: I am getting introduced to BLE and Monkey C. I am a completely newbie.

Thanks!!
