@Kashan afridi This is off topic so I'm not sure if it will get deleted, but usually you don't really need to write anything, for example this comment:
> Bro, we went for medical, they said that these are the vaccination documents, we can open them from you, we send your medical direct to the embassy and we have got the visa, thank you brother
Does not need the "Bro," it has the same meaning if you just started with "We went for medical,...". Some people say dude is gender-neutral, others don't, your best bet is just to use the person's name/username instead
Best of luck with your process!
