You can follow it in the video, but what I always do when that happens, is to lay the rod on the ground and lift the bale arm.
It’s preferable to tugging at a lost cause, where you’ll inevitably lose the fish anyway.
Within a few seconds, the fish was swimming again into open water and that’s where it stayed before I slipped it over the submerged landing net.
I added another tench at the end and that’s in the video as well.
