activityfileattachment and fileattachment entities, do have attachment information associated with the post but i am not able to find it's filecontent although activityfileattachment does have filecontent attribute but it has some GUID in it and there is no information on how to fetch attachment content using that GUID.
1)Here is documentation snap shot of that attribute filecontent of activityfileattachment (https://i.stack.imgur.com/hPl98.png)
2)This is that attachment object i am getting from activityfileattachment entity which has all details except attachment content which i want to download. (https://i.stack.imgur.com/SQXT2.png)
Please Let me know how can i get content of attachment using this GUID given in file content.
If not how can i get/download file content uploaded in a post.
