Thanks both.
I'm with you in that the tab for Inbound payment info must be a customization. I couldn't find it again so probably it was a test from the developers. Nonetheless the main point of my question was to discuss the best procedure to book a payment in local currency for an invoice in foreign currency. I share here below what I have tried so far. Could you give me your feedback on if you do it the same way or if there is a different way of doing this please?
So, I create a payment proposal and create a payment for an invoice totalling 1000USD:

The invoice comes to the payment journal lines in EUR, which already doesn't seem correct - any feedback on if this is expected behaviour?

So I delete the line and start the process of creating a payment proposal again. This time I add more columns to the grid so I can see the amount in EUR according to the exchange rate informed in D365, in this case, 909.09EUR.

In the bank statement I see the bank has applied a different exchange rate as it discounted -920 from my bank account. I would expect the field "Exchange rate adjusment amount" could be editable so I can enter this amout but it is not. Any ideas how to make this field editable?
As I can't edit that field to introduce the 920, as a workaround, I change the exchange rate in the payment proposal:

But still the system still takes the invoice to the payment journal lines as 1000EUR. This should not be the case, should it?
I then go to the general tab of the payment proposal and change the currency there from EUR to USD. This way I can also edit the exchange rate:

I cannot use formulas in this field so I have to calculate outside of the system the rate to be informed. But the problem is that then the system tries to post the payment in USD and my bank does not accept payments in foreign currency. I need to book the payment of this invoice in USD in EUR.
After this, I conclude that it is not possible to do so with a payment proposal.
I try then to pay the invoice with the function "Settle transactions" instead. In this case the system does bring the invoice to the payment journal lines in EUR but it takes as the transaction currency EUR as well so I can't change the exchange rate.

Any suggestion on how people manage payments in local currency of foreign currencies will be appreciated.
Thanks!
