Adding to Bhuvana, you can calculate the size of page-list using either of the suggested functions (LengthOfPageList or SizeOfPropertyList).
After that, you can store this value in a property at clipboard using an activity or populate this value through data transform which can be called pre-processing of flow action. Then you can refer this property in the label field at your section as Bhuvana explained.
