On iOS I think it is correct to first ask in app and then trigger the real thing if the user agrees because in an app there is a context that the app usually needs the permission so it makes sense and I feel it's nicer to ask me first inside the app and usually to explain why they need it at the same time than to take me straight to the real thing without warning because that puts me outside of the app. On websites it might have been ok if they asked in a proper way but presenting something that is pretending to be part of the browser UI when it isn't -- that is, as parent commenter said, a dark pattern.
