We have a bunch of free tutorials. How are you in a coven but they are not teaching you and help you do this? We are not going to do it for you that’s not a thing.
If you make your intro and tell us what you know now, we can give you a best guess working that should work for your level of skill and ability. E.g. can you sense spirit presences, do you have clairvoyance or clairsentience, telepathy, anything like that available to you? You aren’t going to develop those in 10 days, so you may not be able to summon AND sense that it worked, but there are ways that don’t need open senses.

Here is our getting started guide.
You’ll want to get your spiritual hygiene sorted out, and start work on developing your astral senses.
Then when you can know you have a decent chance at avoiding impostors and parasites then try the first contact guides we have on here.
