As some known vulnerabilities exist in the current @openzeppelin/contracts version, consider updating package.json with at least @openzeppelin/contracts@4.4.2 here:
https://github.com/code-423n4/2022-06-nested/blob/b4a153c943d54755711a2f7b80cbbf3a5bb49d76/package.json#L65
While vulnerabilities are known, the current scope isnt affected (this might not hold true for the whole solution).
