Thank you! It's a good idea. But I am not sure If I can query Metamask without the extension popping up. When metamask is already connected, everything is fine but the otherwise the only way of getting this information is querying and querying will trigger the extension popup.

I would love to keep this issue open until finding if there is a way to do or not.

I'v looked up another project VGLoic/metamask-react , method eth_accounts may work.
In file metamask-provider.tsx:

async function synchronize(dispatch: (action: Action) => void) {
  const ethereum = (window as WindowInstanceWithEthereum).ethereum;
  const isMetaMaskAvailable = Boolean(ethereum) && ethereum.isMetaMask;
  if (!isMetaMaskAvailable) {
    dispatch({ type: "metaMaskUnavailable" });
    return;
  }

  const chainId: string = await ethereum.request({
    method: "eth_chainId",
  });

  const isUnlocked = await ethereum._metamask.isUnlocked();

  if (!isUnlocked) {
    dispatch({ type: "metaMaskLocked", payload: { chainId } });
    return;
  }

  // Using eth_accounts instead of eth_requestAccounts may not popup the extension.
  const accessibleAccounts: string[] = await ethereum.request({
    method: "eth_accounts",
  });

  if (accessibleAccounts.length === 0) {
    dispatch({ type: "metaMaskUnlocked", payload: { chainId } });
  } else {
    dispatch({
      type: "metaMaskConnected",
      payload: { accounts: accessibleAccounts, chainId },
    });
  }
}
