Foodsaver question

I’m really excited because I just got a Foodsaver as an early
birthday present.

One question I have is in regards to microwaving in the bags. With
the regular freezer meals you get at the store, it says to puncture
the plastic to vent the steam coming off while cooking. Obviously I
don’t want to poke a hole in the Foodsaver bag, but do you make a
notch near the seal?

or do you not worry about it?

Thanks for the advice!
