Recovery of unsaved 40 minute long video on Samsung A32

I took a video of approximately 40 minutes long this morning at a funeral. I stopped taking the video and waited for it to "process". It took very long, so I switched my phone off. But now I can't find it anywhere on my A32 Samsung. It is not in the recycling or trash bins. I also can't find it on Google photo's. Is there any way that I might be able to retrieve it? I was the only one that took a video, so it is very important to the family.
