Following a guide, the author allow IGMP-traffic with IPtables with the following line:
sudo iptables -I INPUT -p igmp -j ACCEPT
But I want/need to do it with FirewallD. I’ve looked everywhere and got nothing. Can anyone tell me?
Thanks in advance.

I’m uncertain if firewalld has built in support for IGMP. Though you could use firewall-cmd’s direct options which allow you to use a syntax much the same as IP tables. This should do what you’re looking for:
firewall-cmd --permanent --direct --add-rule ipv4 filter INPUT 0 -p igmp -j ACCEPT
