How to import, build and debug secure project for Cortex-M33 in STM32CubeIDE for M33-TD flavor?

I am developing an M33 application on STM32MP257F MPU, I would like to know the steps to import, build and debug secure project for Cortex-M33 in STM32CubeIDE for M33-TD flavor. 
I would appreciate if any one could tell the best and easy way to deploy custom M33 firmware in to this MPU and test it with or without linux?

FYI, I am using STM32MP257F-DK (Discovery Kit) Board.

Thanks in advance,
