How to make custom resolver for create users

[YashvardhanKumar]

I am not able to find a way out how can I make custom resolver on create{TypeName} autogenerated mutation function so that i can add password hashing in it. For example i have a field named "password", I pass the password to the field and hash it and store the hash in the password field. So for that i made a custom resolver but failed to do since the older graphql-neo4j-js had a function named "neo4jgraphql".

createUsers: async (
      some: any,
      params: any,
      ctx: any,
      resolverInfo: any,
    ) => {
      console.log(params);
      const dat = JSON.parse(JSON.stringify(params.input[0]))
      console.log({dat});
      
      
      // params.hash = await argon2.hash( params.hash );
      const findUser = await ctx.executionContext.executeQuery(`
      
        CALL {
        CREATE (createe:User)
        SET
        createe.id = "${dat.id}",
        createe.name = "${dat.name}",
        createe.email = "${dat.email}",
        createe.username = "${dat.username}"
        RETURN createe
        }
        RETURN createe { .id, .name, .email, .username } AS data`);
      // if ( findUser.records.length > 0 ) {
      //   throw new ApolloError( 'This user already exists', "200", [
      //     'user_already_exists',
      //   ] );
      // }

      console.log(findUser);
      let info: CreateInfo = {
        nodesCreated: params.input.length,
        relationshipsCreated: 0,
      };
      let a: CreateUsersMutationResponse = { info, users: findUser };
      console.log(a);

      return a;
      // return neo4jgraphql( obj, params, ctx, resolveInfo, true );
    },

I request the team to please make an alternative function of the "neo4jgraphql" function or if there is any, please guide me for the same. Since the package has deprecated, i am not able to use it and i can't find any supporting threads as of how i can do it
