arcgis 10.5 - Adding vertex to line at point location using ArcPy?

I have a line layer and point layer on my ArcGIS project. The points are on the lines. I want to create vertex on lines at this point coordinates.

import arcpy

point_rows = arcpy.da.SearchCursor("D:\Test.gdb\MyPoints", ['OID@', 'SHAPE'])


rows = arcpy.UpdateCursor("D:\Test.gdb\MyLines")

for row in rows:
    geom = row.SHAPE
    for part in geom.getPart():
        for pnt in point_rows:
                row.X = pnt.X
                row.Y = pnt.Y
                rows.updateRow(row)

I could not add vertex on points, if point is on the line. How can I do this using arcpy?
