RPM fusion GPG check FAILED Fedora 33

I want to add fusion repository on my custom Fedora 33 template VM with this commandline :

sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm

but after that I have this message :

Is this ok [y/N]: y
Downloading Packages:
warning: /var/cache/dnf/commandline-d27c1cfc10149c68/packages/rpmfusion-free-release-33.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID d651ff2e: NOKEY
Public key for rpmfusion-free-release-33.noarch.rpm is not installed
Error: GPG check FAILED

How to resolve this ?

Thank you.
