What is the major product formed when propene reacts with $ICl$?

Consider the following reactions:
$X + HCl \xrightarrow{\text{Anhydrous } AlCl_3} C_2H_5Cl$ (Addition)
$Y \xrightarrow{\text{Anhydrous } ZnCl_2 / HCl} C_2H_5Cl$ (Substitution)
$Y$ can be converted to $X$ on heating with $...$ at $...$ temperature:
