Slight crack in a Huawei Mate 10's screen, what is best to do?

I noticed today that my Huawei Mate 10 Lite’s screen is slightly cracked at the edge after I hastily put it in my pocket yesterday (I usually carry phones in my backpack) and then proceeded to run around with the same phone in my pocket. The resulting damage can be seen on the picture below, and I am not exactly sure what to do. I am not very concerned with looks, but I am worried about small pieces of glass falling out. At the same time, I am not sure if something as drastic as screen replacement is necessary. Is there any way to hold the small piece at the crack together so I don’t have to put out money on more expensive repairs? What sort of thing would the other fixers recommend in this case?
