Find My app played sound on iPad when not requested by anyone on the Family Plan

We were all sitting, watching TV and the iPad Find My app sound goes off and says someone was trying to locate it. No one on the Family Plan (My husband was sitting next to me, no technology turned on) activated this request. I see that over 100 people have had similar issues to a same question in 2019. Same screenshot is what I received in my email account, too.

Very concerning, as many responses say that it's by someone on the plan, and cannot be done unless the equipment is jailbroken.

The iPad is not jailbroken.

Again, no one on the Family Plan requested this sound/feature, so looking to see how this would have been activated if this is the case.
