The file is from a slack server export file, so the structure varies every time (if people responded to a thread with text or reactions).
I have tried several SO questions, with similar problems. But I guarantee my question is different. This one, This one too,This one as well

The issue is that there are several keys that vary, so the structure changes within the same json file between messages depending on how other users interact to a given message.
