GSN high and critical issues

Hello,
I'm trying to follow the [steps to send gasless TXs] (https://docs.openzeppelin.com/learn/sending-gasless-transactions), but running npm install @openzeppelin/network produces 49 vulnerabilities (3 low, 19 moderate, 26 high, 1 critical). Running npm audit fix or npm audit fix --force does not resolve these issues. One known issue is 'Insecure Credential Storage in web3'. Are there updated libraries that I can use instead?

Many thanks for your help on this!
