DA14583 not found in Smartsnippets

Hello,

I use the DA14583 in my own design.
For developing I use Keil ULINK Pro on the Pins SW_CLK (26) and SWDIO (25).
I can download the software from uVision and start it properly and now I want to write the code into the flash
As far I have seen this is not possible from Keil uVision 5.15 directly, it seems I need Smartsnippets.
I installed Smartsnippets V3.9, 64Bit and expect using Keil ULINK Pro as well, but when I start Smartsnippets, the project and virtual com port / JTAG selection opens but I can not see my board.

Can anybody can help me how to flash the code?
VCC_FLASH (Pin 5) is on VCC

Thanks
