[2013 XC60] Where is the evaporator drain tube at?

[2013volvoxc60]

I looked under the car and couldn't see where it was draining from. This product I got requires me to shove this tube into the drain all the way up to the evaporator and spray it's load all over it.

Alternatively, is the evaporator located in front of the cabin air filter? If so, I could take the filter out and spray the evaporator from there.
