I recommend gving more detail about the plugin other than the name so that staff know if its worth adding it or not. Plus, it doesn't look like its 1.16.1 compatible.
Currently the /dl command on Minehut will not work if your world is greater than 100mb.
Alternatively you can use a client side world downloader or schematica.
VERSION 1.16.1 CONNECT bedrock.minehut.com
PORT 19132 DEVICES iOS, Android, Win10
Keep in mind, Bedrock was down for most users, but a patch has been put out. I havn't test this myself so let's hope it works.
If they work on your single player 1.16.1 world and don't work on Minehut 1.16.1 world... I can only assume its because of the PaperSpigot it's running.. and there's nothing you can do about that.
