2. Rename the Generic.kl to Generic.txt

3. Open this file with an text editor

5. Change it to whatever you want. I simply tried following: # input_fw Intelligent Key for Dream key 703 ASSIST

6. Rename it back to Generic.kl (otherwise you won't be able to press any hardware button after reboot)

7. Check permissions

8. Restart your device

For now, Bixby is used Google Assitant with item display on the screen
