Looks good, just a couple of small changes requested.

I still need to test it out locally, but I wanted to ask which platforms is the Ledger Connect not available so that I can also try out the WalletConnect functionality?

Sorry for not including that on the PR description. You can test the WalletConnect support on Chrome; the Extension is currently only available on Safari iOS and macOS.

We've released the final version of Connect Kit and I've updated the package dependency.

Please update the package.json for packages/ledger to:
