How to get Panel to use properties from a PropertyGroup?

Question

I'm trying to create a PropertyGroup so that I can share my addon's properties between several different panels and operators. The below is the best I came up with based on the info I could find, but it's not working, but none of the properties I'm adding in my draw() method are displaying. How should I go about doing this?

import bpy
from bpy_extras import view3d_utils
class NormalToolSettings(bpy.types.PropertyGroup):
    brush_type : bpy.props.EnumProperty(
        items=(
            ('FIXED', "Fixed", "Normals are in a fixed direction"),
            ('ATTRACT', "Attract", "Normals point toward target object"),
            ('REPEL', "Repel", "Normals point away from target object")
        ),
        default='FIXED'
    )
strength : bpy.props.FloatProperty(
    name="Strength", description="Amount to adjust mesh normal", default = 1, min=0, max = 1
)

normal : bpy.props.FloatVectorProperty(name="Normal", description="Direction of normal in Fixed mode", default = (0, 1, 0))
target : bpy.props.StringProperty(name="Target", description="Object Attract and Repel mode reference", default="")



#---------------------------
class NormalToolPropsPanel(bpy.types.Panel):
"""Properties Panel for the Normal Tool on tool shelf"""
bl_label = "Normal Tool Properties Panel"
bl_idname = "3D_VIEW_PT_normal_tool_props"
bl_space_type = 'VIEW_3D'
bl_region_type = 'UI'


def draw(self, context):
    layout = self.layout

    settings = bpy.props.PointerProperty(type=NormalToolSettings)

    obj = context.object

    row = layout.row()
    row.prop(bpy.context.scene.my_tool.brush_type)

    row = layout.row()
    row.prop(bpy.context.scene.my_tool.strength)

    row = layout.row()
    row.prop(bpy.context.scene.my_tool.normal)

    row = layout.row()
    row.prop(bpy.context.scene.my_tool.target)


#---------------------------
def register():
    bpy.utils.register_class(NormalToolSettings)
    bpy.utils.register_class(NormalToolPropsPanel)
bpy.types.Scene.my_tool = bpy.props.PointerProperty(type=NormalToolSettings)



def unregister():
    bpy.utils.unregister_class(NormalToolSettings)
    bpy.utils.unregister_class(NormalToolPropsPanel)
if name == "main":
    register()

----Edit Was able to fix the code. Appending it here, since the question has been closed:

import bpy
class PG_NormalToolSettings(bpy.types.PropertyGroup):
    brush_type : bpy.props.EnumProperty(
        items=(
            ('FIXED', "Fixed", "Normals are in a fixed direction"),
            ('ATTRACT', "Attract", "Normals point toward target object"),
            ('REPEL', "Repel", "Normals point away from target object")
        ),
        default='FIXED'
    )
strength : bpy.props.FloatProperty(
    name="Strength", description="Amount to adjust mesh normal", default = 1, min=0, max = 1
)

normal : bpy.props.FloatVectorProperty(name="Normal", description="Direction of normal in Fixed mode", default = (0, 1, 0))

del bpy.types.Scene.my_tool
