You will need to warm up gently the glass being careful not to damage the screen, provide some protection. As it fits very tight in its slot a very thin metal spatula such as those used for painting that are relatively easy to get and quite cheap will help. You’ll need to lift up the strip rather than sliding anything under it as you have screen flexes running under that and the risk of damaging screen for good is quite high. An acrylic replacement can be found on eBay and probably Aliexpress.
