>From the shell, you have to escape the quotes, ie.

/sbin/nft insert rule filter input log prefix \"nftables \" drop

Anyway: I recommend you use nft -f for this purpose instead of using a shell
script since this is breaking atomicity, eg.

#!/usr/sbin/nft

flush table filter
insert rule filter input log prefix "nftables " drop
-EOF-
