You can create a presets with any of the delays algorithms (#104 to #114) feeding (series routing) 180 St-Diffusor or #181 DiffChorus…or use #182 Tapdly+DiffChorus which is already made of delays and diffusor.
For non swirling Chorus, you should try Micropitch preset, Any pitch shifter or detuner with a few cents detuning (+/- 8>12 cents) with some added delay (within 25 ms) will do the thickest chorus possible.
all the best
