If the ZOOM module is restored after deleted, it will be registered as a new video lecture.

Accordingly, it's not possible to restore the attendance records of the video lecture that was previously conducted.

(Note) Due to the linkage with LMS(Moodle)-ZOOM, deleting ZOOM from LMS(Moodle) means that the vieo lecture created in ZOOM  is deleted through the API,  simultaneously the attendance data previously imported into the LMS  is deleted.

In this case, you can check the  participant records of video lecture on the ZOOM site.
