On my ZTE Axon 7 I had four fingers configured to start specific apps when the corresponding finger was pressed. That was very practical to be able to start an app like Evernote directly. On that device that could be specified in the setting and that setting seems to be missing on Pixel 3.
Is there a way to do something similar on the Pixel 3 (with Android Pie)? (It's even okay if I have to write code.)
