Stuck at Installation Step 3 Get SSH Key

Hello,

Anyone can help?

I am stuck at Installation for:
CONNECT TO INTEL® FPGA DEVCLOUD
Use a Secure Shell (SSH) client terminal to begin.

Step 3: Get SSH Key

You're almost done! To start the process, download an SSH key by pressing the button below:
SSH Key for Linux/macOS/Cygwin

After clicked SSH Key for Linux/macOS/Cygwin, downloaded devcloud-access-key-76597, what shall I do next in order to get to MobaXterm Terminal.

Thanks.
