Github issue integration won't integrate comments to monday item updates

Hi. I created a (github app) Integration that will create a new board item when a github repository has a new issue created. In the field mappings I specify mapping Body → Item update. This will allow an integration to occur such that the initial github issue description gets mapped to an item update. However… if I create any comments on the github issue , they don’t appear in the previously created item on monday.com. Why? This seems so basic a feature.
