How to obtain the permission change information of member in GitHub

Objective: To obtain the permission change information of members in a specific repository in GitHub, for example, the permission of developers ‘A’ is upgraded from read to write.

Question: Through the GitHub document, I found that GitHub-Api list-repository-events can obtain MemberEvent, which contain the information about the organization’s member changes. However, all MemberEvents obtained do not have the “changes” attribute (it contains that the changes to the collaborator permissions if the action was edited). How can I get the “permission change information of project members”?
