Which accent should I choose?

Are there platforms where you can choose an accent, for example, to learn British or American English, and receive targeted assignments for this?

 

I'm a fan of British English. It's important for me not just to speak correctly, but to sound like London, not Texas. The problem is that most courses don't make distinctions. But on the promova price platform, I found exactly what I was looking for — you can choose an accent, and then receive assignments, dialogues, native speakers, and even a transcription that matches your speech style. It's not just convenient, it's respect for detail.
