Need a clicker for PowerPoint/Keynote

[Videomanmac]

So I'm browsing for a clicker to control my PowerPoint and keynote presentations for class, and I was intending to buy the Apple Remote, but I learned that my 2015 15" MacBook Pro is not supported.

I do have an Apple Watch, and read that tr can be used as a clicker, but not on the Mac.

Anyone have any cheap clicker for Mac that they use?
