Electronic – Need help how to disconnect this (pictured) connector inside a tablet computer

I need to remove and replace the battery inside a tablet computer (a Nuvision TM800W560L, circa 2015-2016).

Between me and the battery lies a flat, flexible PC board style (ribbon?) cable terminated in a (tiny, delicate) connector (the end pictured is a bit more accessible.) A photo is attached/below.

I certainly do not want to damage the connector during cable removal and re-insertion!

What is this type of connector called, and how should it (properly) be disengaged from the cable (so it can be re-engaged later)?

Thank you for any advice!
