Triggering google assistant/siri/alexa with HID code?

[embedded_newbie]

I want to trigger Google Assistant/Siri/Alexa on the push of a button. I found the HID code for the home button, but I presume long pressing this will not send anything to the device to trigger voice assistant. Has anyone worked on this problem before?

Hi,

Please check out how this is done in the Smart Remote 3 application.

It sounds like you can use that as reference.
