It seems that in order to add the token, I would have to be logged in (on the codecov site) to access https://app.codecov.io/gh/TheAlgorithms/JavaScript/settings ? I'm slightly uncomfortable with this as it requests permission to "act on my behalf":

Yes.

I agree.

I bit the bullet and authorized CodeCov to obtain the token, but it turns out that I can't edit repo secrets since I do not have "admin" permissions. This will require @Panquesito7 or @AnupKumarPanwar I believe.

@appgurueu You should have admin access to the repository now

Just in case: please make sure that CODECOV_TOKEN is also added to the dependabot secrets (6e27235fb75298833448ba1b23e5178f7eea2290 adds dependabot).

Why would dependabot need the codecov token? It seems to work as-is: https://app.codecov.io/github/TheAlgorithms/JavaScript/commit/9010481c2930d65621f18f41c216f29fceaa8807

Without it, the UploadCoverageReport will fail for each PR created by dependabot.
