❔ Access page behind Azure OAuth using HttpClient?

I've recently implemented OAuth on my Azure hosted site and need to find a way to access one specific page only of it now via c# (have been using HttpClient until now).Would it be easier/better to exclude OAuth on that page (very obscure url) or use a tenant/clientid/secret instead? I'm unsure of best way to achieve accessing that one page now. How would you approach this?
