Good afternoon!

How is the component that displays the task of the business process customized?

For example, I need to display an additional button by clicking on which a slider with the information I need will open.

Where can I set this button? Write a custom activity?
Does activation affect the output of the task?

Changing the standard BP task templates is not provided, only the creation of your own activity, with your own task form.
Here is an excellent, official article on the subject.
