The internal reader of the app doesn't give any indication of how far we have progressed within the book.

Describe the solution you'd like

One of the following:

• percentage of the book that we have read so far
• number of pages that we have read / total no. of pages

How will you/everyone benefit from this feature?

It will let me and everyone else know how far they have progressed within the book and how much of the book is still left to be read.

Additional context

The internal reader of the app looks really nice so I would prefer to use it instead lf just switching to some external reader.
