ERC20 tokens do not have receive() or fallback() functions for detecting token transfers.
However, ERC777 tokens are able to detect token transfers using tokensReceived().
Note: MSG.SENDER cannot be verified with ERC777 tokens and that the ERC777 standard is gas intensive: https://github.com/OpenZeppelin/openzeppelin-contracts/issues/2620.

Make sure you are on a public testnet while doing this otherwise the contract deployments will revert. Another good ERC777 tutorial I found: https://www.youtube.com/watch?v=S9nzL_l6D_E
