How to enable IPv6 ping

Issue

I have server with dual stack (both IPv4 and IPv6) configuration. I want to enable ping to the server using both IPv4 and IPv6, but my rules don't work right.

firewall-cmd --zone=public --list-all
public (active)
target: DROP
icmp-block-inversion: no
interfaces: p1p1
sources:
services: ookla http https
ports:
protocols:
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
rule family="ipv6" protocol value="icmp" accept
rule family="ipv4" protocol value="icmp" accept

With these firewall rules (target DROP, ipv6 protocol icmp accepted) server is able to be pinged on IPv4, but not on IPv6.
