How to connect my Alexa motion sensors to home assistant?

I have HA fully setup and connected to Alexa, however, this sends home assistant stuff to Alexa

I need to send Alexa stuff to HA

i.e. I have third reality motion sensors which are connected to echo flexes

I want to be able to send motion detection events from those to HA directly

I know I can setup routines that calls HA scripts but I am looking for a wholesale way of doing it since I have many of those

Can I connect my existing Amazon devices to HA?

Thanks
I was able to see lots of devices but not the motion sensors
Alexa Media Player is open source though so I will look into making a PR
