Answer 1

you haven't imported the plugin for hardhat. Go to your hardhat.config.js and use the following plugin.

require("@nomicfoundation/hardhat-toolbox");

Read the Hardhat documentation for more info on this.

if this doesn't work try to find the specific plugin your need, which in your case is '@nomiclabs/hardhat-truffle5' Try importing this in your hardhat config file.
