How do I check if a user exists in a different connection, when in action script?

Thanks! Indeed I found a way to do this vai sth like this

const ManagementClient = require('auth0').ManagementClient;
      const management = new ManagementClient({
          domain: event.secrets.domain,
          clientId: event.secrets.clientId,
          clientSecret: event.secrets.clientSecret,
      });

      const userRecords = await management.getUsersByEmail(event.user.email);

thanks
