Claim foreign tax credit relief

I have three questions: 1) I have already paid the 2022/23 self assessment tax bill but I just received the notice of payment for HK property tax for 2022/23, am I still able to claim the foreign tax credit relief and what will happend to the tax I have already paid? 2)If I am still able to claim the foreign tax credit relief, the notice for payment of HK property tax was issued on 31 Jan 2024 but the payment is due by 13 Mar 2024, please advice which month of the exchange rate I should use. 3) I also need to pay the HK provisional property tax for 2023/24 by above due date, can this amount be claimed as well in self assessment 2022/23? Thank you.
