Paperclips really aren't ideal for making jigs, you'll end up wearing out the pins in your Switch over time. You're best off buying a high-quality jig, like the one from Team Xecuter.
That being said, if you have a spare ethernet cable laying around, cut yourself a piece off. If you cut off the outer jacket, there are 8 thin wires inside. These are made of a softer copper metal that won't cause as much wear and tear on your pins. They're just about perfect for jigs! Strip about an inch off both ends. For ground, I usually touch one end to either the heatsink or wedge it somewhere on the side of the joycon rail. Then, use the other end of the wire to try and touch joycon pin 10 on the right side. Might take a few tries, but I usually don't have too much trouble with it. For me it's been more reliable than any paperclip, and like I said previously, it's nicer to your pins!
Then install AutoRCM and be done with it. Also, if you do jack up your pins, it's not terribly difficult to buy a replacement rail online and swap it out.
