Technically speaking you should never help chick out of its shell. Hatching is a "test" of fitness. If it can't get out of the egg then it is too weak to live and may even die when it gets older.
With this being said however, i raise just a backyard flock that i like to look at. I do it as a hobby. If i see a chick needs help, i usually help it out a little bit. Ill wiggle the egg to wake the chick up and get it moving. You can also try putting just a little water on it so relubricate the membrane. I actually fully helped a chick out before and she is still alive today and laying eggs. It all depends on your opinion.
If i were you, i would wiggle the egg a little and maybe even open the hole slightly more. Wait a little bit more to see if the chick tries to get out. Just my opinion and technically not the right action but whatever.
