How to join Pom Pom/Snowball Wool

Hi All - was wondering if it is possible to join Pom pom/snowball wool. The balls I bought are only 50g so need to join and can’t work out how to do it. I’m only making a scarf and using stocking stitch. Any help appreciated.

I would join the new ball of yarn on a plain knit stitch that is in between the pom-poms or join it at the end of a row. If you are knitting in a manner similar to this video, I think that should work. and then you would tuck in the yarn ends between the knitted pom-poms.
