How-To Transfer block.io wallet to Electrum

I know literally nothing about bitcoin so bear with me.

I have an old wallet from block.io and am trying to transfer what little btc there is onto a new wallet made with Electrum. I have a backup of my private keys but have no idea how to do the transfer. I was able to import the address, but this creates a watching only wallet that from what I read doesn't actually transfer anything? I have 2 keys, which the doc details:"Each address requires two private keys. The first key is BIP32-derived, and the second key is fixed". I have no idea how to use these 2 keys to transfer my wallet. If anyone could help, does anyone have experience doing this transfer?

Below is the "general use" info if it helps:

General Usage: The data below provides you with everything you will need to use your addresses anywhere you deem fit. The addresses in your Block.io account are multi-signature addresses of the type P2SH, P2WSH-over-P2SH, or P2WSH. Each address requires two private keys. The first key is BIP32-derived, and the second key is fixed. You can use any BIP32 tools to determine private/public keys for your addresses at depth i, where 0 submitted by
