Help with seed stitch

I have been working on a cardigan sweater for the first time, and it is my first experience with both the seed stitch and button holes. My pattern is having me do a button hole with these instructions: Seed 2, YO, Seed 2tog, Seed 1. So, I sort of understand that seed stitch is knitting the purls and purling the knits, so how do I “Seed 2tog”?
Any help is greatly appreciated! Thanks so much!

To seed st2tog, either k2tog or p2tog, depending on what will keep the pattern for the following sts. The buttonhole interrupts the pattern a bit but you will be able to re-establish the pattern in the next row.
