When an image is saved in SharePoint, I post the image thumbnail to Teams
Post a Flow Bot to Teams using "Thumbnail Large" as shown in the following figure.
Each time a file is created in Sharepoint, a message is posted to Teams.
But when I looked at the same post on Teams a day later, I couldn't see the thumbnail image.
Do thumbnail links cause broken links after a day? If you have a solution, please let me know.
*Of course I have confirmed that the original files are on SharePoint.
