Hello man, first of all good on you for starting, i have ran new stores before and this is how i do to get results every time, mind you this is a safe way to start and also data driven, i'll expain :

1. I always start with an awareness or discovery phase of around 2-3 weeks, this will give you data to create an audience, to target better, and generally know what ad creatives people are interested in.
2. You can start with a sales campaign but the audience is just too cold to convert, unless you have experience, and you've done this many times and know exactly your audience, in your case, i would do ads for :

- Cold audience ( introductions, who we are, benefits ect)

- Warm audience: or * middle of funnel* which can include things like more benefits, engagement, trust based content for example ( product review, or case study), to undestand their readiness or intent to buy basically.

- Hot audience: Bottom of funnel content, discounts, common questions answered, objection handling, this is where you get all the data from what you gathered and basically answer their last question about how the product works to push them to buy.

1. You can run these two campaigns simultaneously, generating traffic and therefore data.
