Checklist tasks library what is the usage?

Hello,

what is the the usage of “a task library “-in checklists .? under : Checklist template - main menu - “task library “?

Is it generic tasks that we can create and use the SAME EXACT task in many “enterprise boarding steps “? (related to many different enterprise onboarding STEP ?

And can we use it by selecting “select and add task” under the creation of tasks ?

See attached file.

Thanks a lot

Revital.
