Sometimes, bridging time may take for 18-20 minutes.
When the order is in the Bridging state, there is no mentioning about the approximate time to wait until the bridging is completed.
It would be nice to show it on the Progress bar and in the Account modal

Possible option: store the estimated value in the local storage and display it on the UI when order is in Progress

One more possible option from @anxolin :

I think we should reach them and ask them to add it. Worst thing we can add it ourselves in the SDK, if Gnosis bridge always takes 30min, they are not adding more bridges anyways
