Share options of Denmark Company

I'm now live in UK and UK tax resident. I'm under the basic tax rate on income tax because I worked start from Feb24 to Jun24, now is unemployed. I just exercised and sold my previous company share options with some gains, which provided to employees (Denmark listed company) these days. My Questions are: (1) My previous home country will tax me the sell of share options as income tax. May I know if I can apply tax relief for that part on HRMC? (2) May I know if I need to pay for CGT? If yes, what's the CGT allowance for Year 24/25? And its CGT tax rate? Thanks.
