wallet_switchEthereumChain Does not work with custom networks #5620

Apparently, wallet_switchEthereumChain doesn't work with networks added through wallet_addEthereumChain
is this intentional?

Steps

Add a custom network

window.rainbow.request({
    "method": "wallet_addEthereumChain",
    "params": [
        {
            "chainId": "0x2329",
            "chainName": "Evmos",
            "nativeCurrency": {
                "decimals": 18,
                "name": "Evmos",
                "symbol": "EVMOS"
            },
            "rpcUrls": [
                "http://localhost:3000/api/eth-json-rpc/evmos"
            ],
            "blockExplorerUrls": [
                "https://escan.live"
            ]
        }
    ]
})

(this works, this adds the network to my wallet, it doesn't auto switch to it after that though as is the behavior in other wallets)
2. Try to switch to the network

window.rainbow.request({
    "method": "wallet_switchEthereumChain",
    "params": [
        {
            "chainId": "0x2329",
        }
    ]
})

I get the following error

{
    "name": "Invalid Request",
    "message": "Chain Id not supported",
    "code": -32600
}

digging the code a little bit it seems that only what's in this list here is supported, is that correct?

wallet_addEthereumChain seems to check for a featureFlags.custom_rpc flag, but wallet_switchEthereumChain right below it doesnt
