Qlik Sense - Single date filter for different dates using canonical dates

[mvgadagi]

Hello Everyone,

I am new to Qlik Sense  and I need help in creating the single date filter for the different date dimension,

I currently I have the data model as below

Tasks Table

taskid	taskname
1	First Task
2	Second Task

Tasks Dates

taskid	task_created	task_paused	task_stopped
1	2019-01-01	2019-04-15	2019-06-10
2	2019-03-01	2019-04-10	2019-06-16
3	2019-06-01	2019-06-15	2019-06-28

Now I wanted to create the single date filter which should be able to do the job for all the three dimensions i.e. task_created,task_paused,task_stopped.

I have gone through below posts but I do not succeed to achieve this, Can you please guide me?
