How to select Claude chatting style on the web?

So... Not sure really where to post this.
I tried Claude AI very late but I have been blown away by its depth, in the bigger conversation style. I love the ios app, it's honestly the best among all ai apps I've tried, chatgpt, gemini and perplexity.
How do we change the style on the web version on mac? The lack of headings is less of a problem but if we can't reliably change the style mid conversation...
Like in the prompt style before the first message I see 5 options but they are not quite the same thing that we have on mobile?
Thanks!
