BorgBackup: fuse: failed to exec fusermount3: No such file or directory

I'm trying to run the borg mount in Borg Backup, but it's saying that fusermount3 is not installed. fuse: failed to exec fusermount3: No such file or directory Googling this problem isn't helping. I have fuse installed: fuse is already the newest version (2.9.9-3). as is libfuse: libfuse2 is already the newest version (2.9.9-3). I'm running Linux Mint 20 with Kernel 5.4.0-113-generic
