How do you handle vacation?

Although I am not going away until several months (July) I was wondering how you handle the doses on Vacation? I am traveling to Africa and will be there 3-4 weeks. I'm on the compound Semaglutide which means I am injecting a needle which may be an issue. But I guess I can just put it in my luggage-hope the few days in heat does not spoil it? May have to find a way to keep it in the iced container they send me through mail?
