call recording recovery 1 -- 2

I am trying to recover a call recording file that i had almost 5 months ago. I use an application called "call recordings" from appliqato ([login to view URL]) but with app I can only record up to 300 phone calls. Unfortunately, i lost the file because I did not save it. My phone is Sony Xperia XZ and it has Android 8.0 and rooted. Do you think there is a way I can recover this particular phone call recording? I have tried many apps and software but I do not believe that are authentic and helpful. Now I am at stage that my phone is at factory reset because I did the root. Awaiting your positive reply.
