Which is the best macro lens for Canon EOS R5 users?

So my parents got me this Canon EOS R5 for my graduation and I know its way more camera than I actually know how to use yet but I really want to start taking those super close up shots of the bees and flowers in my garden this spring. I think they call it macro photography? I'm totally lost looking at all the lenses though because some are really expensive and some are cheaper and I dont know if they even fit my camera. My budget is probably around $1000 since I'm still a student. Im sorry if this is a really basic thing to ask but what lens should I actually get if I want those really detailed bug pictures?
