What are you remapping bixby to?

How did you set it to flashlight? I tried setting the key up this way but the Flashlight app was not available to select.
 
I've remapped mine to assistant as well. Funny thing though is that I hardly use assistants. I NEVER used Siri and only use Google a bit more. What I DO use though is the Google feed that is typically on the left screen on Pixel devices. Should probably just remap to that.
