Chorus and reverb add space
Effects come after the synth. The Mod FX block's Chorus plays slightly delayed, wobbling copies of the sound, so it shimmers and spreads.
Reverb adds the echoes of a room, so the sound seems to sit in a space instead of right in your ear.
Your turn. Your pad from the last step is ready. Add Mod FX and Reverb so it sits in the same big space as the target.
