Jitsi Meet mute audio and video issue

Question

i'm trying to mute everyone in the conference call to prevent trolling/spamming, but the problem is allowed to umute audio and video at anytime even tho i'm setting the options to be muted by default. P.S : if you have any idea that may help me to prevent this issue from going on into the conference call please just write it down.
