cast mage's blizzard at a specific location

[Aigewen]

I want to cast mage's blizzard at the location that I want. I can call the castspell function and I can see the green circle of blizzard. When playing the game, one needs to left-click on the location and start to channel. However, I don't know if there's a function to left click. Do anyone how to do it?

I'm sure looking into something like SpellIsTargeting is a good one. I usually send the cast and click at the exact same time, no need to wait for it
