I can’t figure out how to combine my ETH from two different networks

Hello everyone, I made the mistake to withdraw my ETH from binance via two different networks. I need to send them in a single transaction in order to make a payment and I really can't figure out how to do that. I'm using OneKey wallet on desktop and it looks like this: https://imgur.com/a/JNTDfEq Any help would be very much appreciated.
