What’s next? (House loan)

We are trying to buy a house. We’ve already had been under contract, had an inspection, the appraisal, uploaded documents needed. What’s next? The lender or realtor haven’t reached out yet we finished uploading the documents last week. We have the down payment still but waiting to see when and how they want us to pay it. Tried emailing the lender haven’t heard anything back. What should we do? Or just wait it out until they reach back out?
