How can I upload the "bleimage_transfer_demo" program on the latest nRF52840 dongle(s140_v7.2.)

I tried plenty of times to upload program on dongle from this site: NordicPlayground/nrf52-ble-image-transfer-demo 

But I got these types of errors as mentioned in attached images!!  (check 1st image which is in SES)

so, how can I upload this program and run the project on this dongle ?

Hello,

This error is reported because the application does not include the optional DFU Trigger Library (USB) library. This just means that you have to press the reset button to put the dongle back into DFU mode, it's not a programming error.

yes, I go through it already !! But my main concern of this program can't give me the desired output on this dongle although it's worked fine on the nrf52840-DK.
