Teensy 4.0 board

Hi,
I am a new user of RemoteXY. But I am very excited to easily creates app in cellular phones.
unfortunately, I can not connect my Teensy 4.0 board https://www.pjrc.com/teensy/td_uart.html to my phone.
I have found a  post about Teensy 3x by replacing the board as Arduino micro, but this case does not work.
Is there any way to solve this problem, or RemoteXY might also add Teensydino models as board in the selection in the website.
I need help on this problem.
