Flight review online tool error

I am trying to review the log using Flight review https://logs.px4.io/
This is the first time I am using this tool.
When I upload .bin file to the mentioned site, it gives an error HTTP Error 400: Invalid File

Can someone explain what is the correct way to do it? From where should I download .ulg?
In the SD card I could only see .bin

Start here:

Good luck.
