Arduino for STM32

hi every one, i have stm32 blue pill with DFU bootloader 2.0 I worked well with it, but lately I have a problem with a essage "could'nt find the DFU device" there's a post on github that fixes this problem (https://github.com/DMaisterra/stm32duino-dfu) but i don't know where i should put this set of files .sh in hardware file in arduino (rogerclark core), i also installed the stm32duino core 2.2 so how i should do with these files please and thans in advance.

Which upload method did you choose ??

DFU bootloader 2.2 but i tried today and the dfu is found, what i did is cut the drivers in the drivers folder in x86 and i reinstalled them there, if the problem repeats i will try to work with the HID boot loader
