Illustrator's Effects Tool

Adobe Illustrator 2021 is brand new to me as of today and I've got it performing in my Ipad Air 3rd generation.  I've drawn a Fresco profile which is the shape of an arch.  And is basically a portion of another piece of work accomplished in PS Elements.  From there and after flattening the layers, I made it my cover in Facebook.  I've decided now the arch would be more appealing if it appeared to be three dimensional.  I'm hopeful Adobe Illustrator will help switch the 2D arch into 3D, and then I'll move it over into PS Elements and repeat some techniques to set it up for Facebook.  What I'd like to know is this do-able using my Ipad.  I'm having difficulty in Illustrator determining how to go about finding the 'effects' in the line up of tool options.  Under the effects I understand revolve and extrude are possibly.  How does one get to effects using Ipad?
