Focus Mode for Podcasting

The only aps i let through while podcasting are slack, which is kind of a back in communication portal. For me, it's a green pair of head phones. The focus mode icon is not san francisco symbol for the briefcase. All the other symbols are san francisco symbols from apple or fontah but that one isn't. I mean, i'm very stingy when podcasting about what gets through to me, because this is the job right now and nothing else is really more important than podcasts.
