Question: Why won't my ERC20 token retain it's name or symbol after deployment?

Hello. I am trying to deploy a very simple ERC20 contract onto the Cronos Testnet.

Token name: Commander
Symbol: COMM

I can get Mint, Burn, and Transfer to work, which is great. But the token shows up in people's wallets as

Unknown Token (?)

Screenshot below

This is the OpenZeppelin code. Unchanged when I import into Remix, compile and Deploy

pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/token/ERC20/extensions/ERC20Burnable.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
import "@openzeppelin/contracts/token/ERC20/extensions/ERC20Permit.sol";

contract Commander is ERC20, ERC20Burnable, Ownable, ERC20Permit {
    constructor(address initialOwner)
        ERC20("Commander", "COMM")
        _mint(msg.sender, 123456 * 10 ** decimals());

    function mint(address to, uint256 amount) public onlyOwner {
        _mint(to, amount);

Would I have to verify the contract for it's name to show up?
Any help would be appreciated, thanks.

edit: I've tried setting the name, as well as symbol as Public rather then private. Did not work

abstract contract ERC20 is Context, IERC20, IERC20Metadata, IERC20Errors {
    mapping(address account => uint256) private _balances;

    mapping(address account => mapping(address spender => uint256)) private _allowances;

    uint256 private _totalSupply;

    string public _name;
    string public _symbol;

     * @dev Sets the values for {name} and {symbol}.
     * All two of these values are immutable: they can only be set once during
     * construction.
    constructor(string memory name_, string memory symbol_) {
        _name = name_;
        _symbol = symbol_;

:warning: Seems like you're taking the OpenZeppelin ERC20 code and modifying directly. If this is the case please refer to our guidelines for extending contracts and please read the docs.

You're specifying _name and _symbol, which don't adhere to the ERC20 standard and therefore indexers and frontends won't read it properly.

Use the constructor already included within the ERC20 contract:

// SPDX-License-Identifier: MIT
// Compatible with OpenZeppelin Contracts ^5.0.0
pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MyToken is ERC20 {
    constructor(string memory name_, string memory symbol_) ERC20(name_, symbol_) {}
