Jami sip-client (or dbus) AppArmor problems

I try to configure Jami sip client in ubuntu 20.04 and see in syslog file this message

Jan  1 11:03:08 user-home dbus-daemon[1974]: apparmor="DENIED" operation="dbus_signal"  bus="session" path="/cx/ring/Ring/ConfigurationManager" interface="cx.ring.Ring.ConfigurationManager" member="volatileAccountDetailsChanged" mask="send" name="org.freedesktop.DBus" pid=11820 label="snap.jami.jami" peer_pid=2655 peer_label="unconfined"

I think, it’s linked with AppArmor, and it must be allowed for D-Bus or Jami app, but i can’t understand it, how i can solve it? Thanks!
