Open menu with physical Android menu button

Hello everyone,

I recently started adding support for smaller screens, and there was a weird for striped button in the Android emulator. It’s been so long I used an old Android phone that I thought it was a ‘recents’ button, but off course it wasn’t. When I look on the web, I find a lot of topics on this issue, all ionic-v1. Is there any documentation on how to open the sidemenu when this old button is pressed?

Thanks is advance!
