AutoInput Clear All Autoinput task help plz

Hi everyone
I need some help with an Autoapps ( i presume AutoInput would most probably be used).
I basically want to create a task in tasker using AutoInput that automatically clicks on the "Clear all" button in task manager to clear recent apps.
I am sure this is very easy to achieve for an advanced / veteran AutoApps / Input user, but for a nooblet like myself i have so far just been unsuccessful in my efforts.
Would greatly appreciate it if someone could assist me i creating this task (want to run via Tasker) and i am willing to make a Paypal donation to the successful user whom helps me achieve this, if so desired.
Thanks for reading and in advance.
System info
LG G2
Android 4.4 KitKat ( Cloudy 2.1 ROM)
