Full recording after power went out

This is an unusual ask I believe.

I was asked to co-host and record a legal proceeding.  I started the recording and minutes later the power went out throughout the city.  My internet went down.

I got back online and the meeting had just kept going without me, and the record button was greyed out.  It appears that as I was kicked off, the original host became the owner of the recording.  I had to ask her to pause it at the break.  I then asked her to make me co-host again.

My question is, as we exit this meeting is there a strategy we should employ to make sure I get the whole meeting recording?  We are both still online and haven't left the meeting.
