Feature Request: Customization of Fund Wallet Link

### Describe the solution you'd like

I would like the ability to customize the fund wallet link so that I can put it anywhere in my app.

For example, an app that relies heavily on USDC may want to show the USDC balance of the connected user at all times


Ideally, I would like to be able to give the component children like this:
```

```
or accept a render prop that returns a jsx element
` }`

This would me to follow a familiar UX pattern for depositing funds like in draft kings for example where your balance is always visible and depositing more funds is just a tap away (I cannot wait to make it this easy to get onchain apps funded)


This request is related to #742

### Describe alternatives you've considered.

I've considered placing the balance chip inside of the connect wallet component so that when it is clicked, the wallet dropdown with the funding option is visible. It's a good compromise for now but ideally, I would like the act of depositing to require less mental-load on the user by separating their balancing into a different chip and having one tap to open the deposit flow.
