there is official bot from telegram to update link preview:

Other Video platform like youtube, dailymotion or ... working very well

There is no preview because the platform you have chosen does not provide a preview with the large image similar to YouTube. The same goes for my site, which, despite having set it well, the seo continues to show me the small picture in the previews.
