Basic shapes are not available on the iPad version

For a project, I need to use the shapes tool on the toolbar on the left, I should choose the circle from the Basic shapes library, however, there's no option for that. I cannot use the basic shapes that are on the bottom right under the ruler icon because I need to use the selection and the mask option available under the Shapes tool.

Is there a way to download them (maybe like the other custom shapes available)?

Thanks in advance,
