Create grid from polygon shape - Refined grid

Dear all,
I’ve been downloaded and installed the latest version i-RIC. I want to simulate a river modeling with a nested/refined grid. However in pre-processing step, I did not find the option to generate grid from polygon shape in Select Grid Creating Algorithm (picture attached). Is there any suggestion on which version it was fully provided?.

iRIC does not ensure the safety of the attached file.

    To create a refined grid from a polygon shape in R, you can follow these steps
    Load the necessary packages
    Load the polygon shapefile
    Create a raster layer from the polygon shapefile using the rasterize() function
    Refine the grid by dividing each cell into smaller cells using the disaggregate() function
    Convert the raster layer to a spatial points dataframe using the rasterToPoints() function
