How to prolongue the time of inactive meeting?

Hi, 

I'd like to use a zoom meeting to be in touch with a sick family member while I'm not at home - a laptop with a camera and a mic at home plus zoom app on my mobile in my hand. I've go a pro plan. Unfortunatelly, when the meeting, once started, remains inactive, it's automatically ends after 40 mins. Is it possible to change it for longer or, preferably, cancel the limit?
