Cannot Approve Token For Swap

[Rachel-Eichenberger]

@talonZack think you have to set the permit2 use

function App() {
  <div className="Uniswap">
    <SwapWidget
      permit2 = true
    />
  </div>
}

This issue has been mentioned here, too: #374 (comment)

I can confirm adding permit2 fixes the problem.

<SwapWidget
  permit2={true}
/>

I guess the Issue can be closed. However, I suggest adding it to the documentation of the widget.

Permit2 is a token approval contract that manages token approvals across different smart contracts.

Here is a link to the docs of Permit2, in case you wondered:

@Rachel-Eichenberger But what if we dont want to use permit2? why isnt it working with regular approve?
