@hcho112 LGTM too, your approval was dismissed due to the base branch change since we needed to follow the flow for contributions: https://github.com/near/wallet-selector/blob/main/CONTRIBUTING.md#branching .

Also had to update the description of the PR to include the Type of change checklist to make gh-actions pass.
