Swap issues cannot click on swap

I had ETH in my Metamask account. I have been trying to exchange it from ETH to BNB on the Binance Smart Chain Network. So when I try to swap BNB to ETH. I know that all i have to do is click the ‘swap’ button but it is not available. It is not possible to click on it. as it is not highlighted for clicking.

I am on the latest wallet’s version 9.4.0 (browser extension), I tried logging out then in again.

Kindly help what to do

‘SWAP’ does not work, you need to verify that your network is correct first,
