Julia equivalent of nb_conda_kernels to differentiate environments

I just started using Julia and want to use different environments. So far, I have two environments in two different folders, both with IJulia added to them and then different other packages. When starting Jupyter however, I only see one Julia version as a kernel (Julia 1.5.3).

For Python environments, I use nb_conda_kernels, so Jupyter displays Python[conda env:root], Python[conda env:myEnv], etc. How do I achieve the same with Julia, so i can switch Kernels without switching directories and restarting Jupyter from a different directory?

Since IJulia is using Python you can just install nb_conda_kernels for your Julia installation:

using PyCall, Conda
Conda.add("nb_conda_kernels")

Now you can use the Julia-inbuilt Python to execute any command you need. For an example:

julia> run(`$(PyCall.python) -m nb_conda_kernels list`)
[ListKernelSpecs] WARNING | Config option `kernel_spec_manager_class` not recognized by `ListKernelSpecs`.
[ListKernelSpecs] [nb_conda_kernels] enabled, 4 kernels found
Available kernels:
  conda-root-py           c:\juliapkg\julia-1.6.0-beta1\conda\3\share\jupyter\kernels\python3
  conda-env-3-py          c:\juliapkg\julia1.5.3\conda\3\share\jupyter\kernels\python3
  conda-env-3-2-py        c:\juliapkg\julia1.5.3\conda\3\share\jupyter\kernels\python3
