Writing tool for stacking point features on given co-ordinate

I am trying to write a Python code for creating a geoprocessing tool which will be added as a toolbox in ArcGIS Pro (v2.6).

The tool will

• Ask for a "Target point feature" as input for the (X, Y) coordinates
• Ask for a set of "Input point features" whose coordinates will be changed to the target's coordinates to stack together.

import arcpy

def move_points_to_target(target_feature, input_features):
    # Get the coordinates of the target feature
    with arcpy.da.SearchCursor(target_feature, ["SHAPE@XY"]) as cursor:
        for row in cursor:
            target_x, target_y = row[0]

    # Loop through each input feature and move it to the target location
    for feature in input_features:
        with arcpy.da.UpdateCursor(feature, ["SHAPE@XY"]) as cursor:
            for row in cursor:
                # Update the coordinates of the input feature to match the target location
                row[0] = (target_x, target_y)
                cursor.updateRow(row)


def parameterInfo(self):
    """Define parameter definitions"""
    # First parameter - Target Point Feature
    target_param = arcpy.Parameter(
        displayName="Target Point Feature",
        name="target_feature",
        datatype="DEFeatureClass",
        parameterType="Required",
        direction="Input"
    )

    # Second parameter - Input Point Features
    input_param = arcpy.Parameter(
        displayName="Input Point Features",
        name="input_features",
        datatype="DEFeatureClass",
        parameterType="Required",
        direction="Input",
        multiValue=True
    )

    return [target_param, input_param]


if __name__ == "__main__":
    # Get parameters from tool
    target_feature = arcpy.GetParameterAsText(0)
    input_features = arcpy.GetParameterAsText(1)

    # Call the function to move the points to the target location
    move_points_to_target(target_feature, input_features)

When I added it to my ArcGIS Pro toolbox, it does not ask for any inputs and the parameters seems to go back to default string.

I am just starting to learn how to make a geoprocessing tool.

What am I doing wrong?
