Using Julia in Binder: interactive web environment for running your code

Are both files required? I’m wondering if just Project.toml can be enough
Should I get a uuid for my notebook? (I thought that was only required for package) how should I get it?

Dependencies are CSV.jl, Polynomials.jl, Plots.jl.
How can I get there uuid? (except by going to there Github repository) How can I know the uuid of a registered package? - #6 by Raf doesn’t really answer that.
