Policy with Heart Failure

I am a 27 year old male. I was diagnosed with Dilated Cardiomyopathy in 2020 and have had some surgeries and i'm doing well with it. I am trying to get a life insurance policy but everytime I put down that I have this heart condition it just gets instantly denied. Just wondering where I could go to possibly get a policy. Thankyou Edit: I am from the UK
