Alan Kirks opinion on the Resurrection Narratives?

This is a follow-up question to this post of mine: https://www.reddit.com/r/AcademicBiblical/s/7nZD8ES8dI

As I understand it, Alan Kirk is highly regarded for his work on the development of traditions and memories. What is his position on this? What is his opinion? Does he believe that, similar to the secular scholars, the narratives in the Gospels contain apologetic elements (Jesus allows himself to be touched, eats with the apostles and gives long speeches) and are incorrect memories? Or does he believe that these are older, possibly authentic traditions? (Whether the resurrection is historical or whether the narratives we know from the gospels are based on some kind of hallucination is, of course, a matter of faith that is not permitted in this sub.

Furthermore, I would be interested to know his position and the position of similar scholars on the view of secular scholars that the sightings of Jesus (whether historical or not) did not occur in large groups (with all the apostles at the same time) but were smaller, individual experiences like grief hallucinations, and that the narratives in the Gospels are more theologically motivated.
