After downloading Julia 1.6.1, I figured I might as well remove the 1.5.3 and 1.6.0 kernels that I had installed on Jupyter Notebook, which I did using the instructions here: [How to remove previous version from Jupyter? - Stack Overflow](https://stackoverflow.com/questions/44914176/how-to-remove-previous-version-from-jupyter/45211705)

But now I’m having trouble getting the 1.6.1 kernel installed. After downloading 1.6.1 I went to the Julia command line and tried `using Pkg` and then `Pkg.install("IJulia")`, just like how I originally got the Julia kernel in Jupyter. Based on the REPL response, it appeared to have installed correctly, but when I go to create a new Jupyter notebook I don’t see an option for a Julia kernel…Any suggestions for how to get the kernel back?
