...you can't using a single command (unlike photoshop)...
...you have to create it manually, either by importing a PSD with the effect you need, set to multiply or darken...
...the other option is to create it in illustrator with a white filled shape (no stroke) set to inner glow, color black, edge setting active, then multiply or darken the filled shape...
...you then need to create a clipping mask to clip the shadow and offset/resize it to mimic that of photoshop...
