You cannot directly view messages exchanged between learners and tutors within Aptem. This is to protect the privacy of both parties and maintain confidentiality.
However, to monitor the learners' progress while the tutor is on sick leave, an interim tutor can be assigned to manage those learners until the current tutor returns. Once the tutor is back, the case owner can be changed accordingly.
This can be accomplished through the learners' profiles in the classic or console interface, please see screenshots below.

Please note: Assigning an interim tutor only allows them to view messages sent by learners after this change. They will not be able to access historical messages exchanged between the original tutor and learners.
