How-to guide for adding upgradeability to ERC 20 contracts

I am using OpenZeppelin TUP strategy to upgrade the smart contracts. However, I have used my custom ERC20 contract. The upgrade feature that I have added in the ERC20 contractV2 is to change the name and the symbol.

In this project I have created an ERC20 with a multi wallet approvals upgradable contract. Without the approval of more then 2 owner the mint function will not work. In upgradable contract I have created 2 functions to upgrade 1.Change Name 2. Change Symbol.

This repository contains the basic implementation of Transparent & UUPS proxy patterns using Openzeppelin Upgrades Plugin.
