Yeah ,but nothing is different than your original script you posted like 4-5 threads ago. The only changes is what other people have posted.

import bpy


def confirm_testmat_group():
    #reference to the nodegroup instance
    for mat in bpy.data.materials:
        #This gets only 'TestMat' material 
        if mat.name == 'TestMat':
            node_ref = mat.node_tree.nodes['Group']
            return node_ref


class TestMaterial_PT_layout_panel(bpy.types.Panel):
    bl_label = "Test Material Node"
    bl_category = "Test Material"
    bl_space_type = "VIEW_3D"
    bl_region_type = "UI"
    
    #replacement for the draw function of your panel:
    def draw(self, context):
        layout = self.layout
        #layout.operator("test_material.add_material", icon='IMPORT')

        #if node group found, draw all input properties                                
        if confirm_testmat_group():
            node_ref = confirm_testmat_group()            
            for i in node_ref.inputs:        
                layout.prop(i, 'default_value', text=i.name)


classes = (TestMaterial_PT_layout_panel,)


def register():
    for cls in classes:
        bpy.utils.register_class(cls)


def unregister():
    for cls in classes:
        bpy.utils.unregister_class(cls)


if __name__ == "__main__":
    register()
