Large videos from Discord fail to preview with M_MEDIA_TOO_LARGE

[SethFalco]

A member on Discord uploaded a 100 MB ~ video, which was bridged over to Matrix.

However, we just see a broken preview:

If I try to download it, I get a file named like the video (including the .mov file extension) but it's only 79 bytes, and contains the following:

{"errcode":"M_TOO_LARGE","error":"Too Large","mr_errcode":"M_MEDIA_TOO_LARGE"}

If I preview the message and check the external_url, it contains the video file from Discord which I can just download and watch.

I assume it's because the file is larger than a limit set either on the bridge, homeserver, or web server. Is there a way this can be handled more gracefully, for example just send the literal Discord link as-is if the file is too large?
