worsksheet.clear() is not clearing the formatting on the cells it is only clearing the values is there a way to clear the foprmating too either on all cells or a specified range

i have tried cellformat bold none and passing it to the format func of gspread but its not working
here is my code that i havev tried

if len(list_of_lists) != 0:
    num_rows = len(list_of_lists)
    num_cols = len(list_of_lists[0]) if num_rows > 0 else 0
    start_cell = 'A1'
    end_cell = gspread.utils.rowcol_to_a1(num_rows, num_cols)
    print("start cell",start_cell,"end cell:", end_cell)
    data_range = f"{start_cell}:{end_cell}"
    print("data range",data_range)
    clear_format = cellFormat(
    backgroundColor=None,  # Clear background color
    textFormat=textFormat(bold=False, foregroundColor=None),  # Reset text format
    horizontalAlignment=None  # Reset horizontal alignment
    )
    format_cell_range(worksheet, data_range, clear_format) 
    worksheet.clear()
    print("Formatting cleared")
    cleared = True
