Type conversion of interface slices in Go: how to convert []interface{} to []string?

Hello everyone! I'm new to Go and I've encountered a problem that seems very strange to me. I have a function that takes `[]interface{}` (a slice of interfaces), but I need to pass it to another function that expects `[]string`.
