Missing or invalid. request() method: eth_sign

Bug Description
Clicking "Confirm swap" on https://app.uniswap.org/#/swap fails silently with Gnosis Safe connected via WalletConnect.

Steps to Reproduce

1. Connect the Gnosis Safe mobile wallet to app.uniswap.org using WalletConnect.
2. Enter any amount of OETH to swap for ETH.
3. Approve the allowance.
4. Click "Confirm swap".
5. See uncaught error in the console.

Expected Behavior
The wallet should present a prompt for signing the swap transaction.

Additional Context
It's possible that Safe + WalletConnect is not supported. I think 1inch requires me to use the Safe App within their web interface. Other dapps allow me to do what I'm attempting to do here.

Also seeing this attempting a trade of ERC20s after successful allowance approval on walletconnect v2:

Native assets (ETH, AVAX) seems to be working fine.

Looking the in the source code, this may have been addressed previously:
https://github.com/Uniswap/interface/blob/main/src/connection/WalletConnectV2.ts#L38

Some useful information that may assist in resolving this - use methods instead of optionalMethods:

Also noting that trustwallet was able to trade successfully via walletconnect so this seems wallet dependent.
