Identifying the Time of an MR Description Change Based on a particular Text Change

I wanted to identify the time when an MR description was changed based on some text change in it.

Using current python Gitlab API , I can only get the details/list of “changed the description” part in an MR. but I am not able to get the changes/contents added/removed at that particular MR description change. Is there any other methods in Python gitlab api using which I can extract this info? or any other coding technique to extract this information.

Thanks in advance and I appreciate your time on this query.
