What does this mean

Hi

I swapped mto for eth on uniswap, gas fee is taken transaction says is complete but tokens have not been swapped from mto to eth


What does approve mean and I can’t approve anything as there are no links or buttons to interact with.

Here is my transaction details on etherscan
https://etherscan.io/tx/0xdd42288a14f0c16dfeb3c908cad1f24ae0704e0265c9eec6afc96676d21c6694

Please advise
