Need help using the Simple_Hair_UV script for creating hair uvs

Im using the Simple_Hair_UV script found in the Xgen UE documentation however when i imported my IGS alembic file that i exported, it has 3 different description and multiple splinegrp .
How do i add multiple groups and curves in the script?
Tried using " ; " and " , " in between each group and it doesn’t work.

https://docs.unrealengine.com/4.26/en-US/WorkingWithContent/Hair/XgenGuidelines/

Here is the part i am having trouble with, it's using Python.

curve_top_group= 'Herc_Flyaways|Herc_Hair_SplineGrp0 , Herc_HairBlend|Herc_Hair_SplineGrp0 , Herc_Hair|Herc_Hair_SplineGrp0'

It keeps giving me error, here is how the outliner looks like

Herer is the default script:

from maya import OpenMaya
import os

def create_root_uv_attribute(curves_group, mesh_node, uv_set='map1'):
    '''

    if not cmds.objExists(curves_group):
        raise RuntimeError('Group not found: "{}"'.format(curves_group))

    # get curves in group
    curve_shapes = cmds.listRelatives(curves_group, shapes=True, noIntermediate=True)
    curve_shapes = cmds.ls(curve_shapes, type='nurbsCurve')
    if not curve_shapes:
        raise RuntimeError('Invalid curves group. No nurbs-curves found in group.')
    else:
        print "found curves"
        print curve_shapes

    # get curve roots
    points = list()
    for curve_shape in curve_shapes:
        point = cmds.pointPosition('{}.cv[0]'.format(curve_shape), world=True)
        points.append(point)

    # get uvs
    values = list()
    uvs = find_closest_uv_point(points, mesh_node, uv_set=uv_set)
    for u, v in uvs:
        values.append([u, v, 0])
        #print (str(u) + " , " + str(v)  )

    # create attribute
    name = 'groom_root_uv'
    cmds.addAttr(curves_group, ln=name, dt='vectorArray')
    cmds.addAttr(curves_group, ln='{}_AbcGeomScope'.format(name), dt='string')
