Get another user IG Media by ID

Hello facebook community, I have a question regarding the GET IG media by id endpoint. I have a webhook that sends me the media id of my account whenever someone tags me in their post. The webhook notifies me with the media_id of the post in which I was tagged. Is there any chance that I can get the media content by id using my access token? Otherwise, what use do I have with the media id that I get notified with? Currently if i do https://graph.facebook.com/v19.0/{media_id}?fields=media_url&access_token={access_token} it says that the object doesn't exists. Any solutions here? Thank you!
