How to use IN in a raw Eloquent query?

Question

Laravel

Good day to all!
There is a system that uses raw user requests to the database and returns their result. The code is quite simple:

$results = DB::connection('mysql')->$queryType(DB::raw($q->QueryText), $params);

The $params variable contains an associative array with variables passed in by the user.
This works as long as IN is not used in the query.
Here a problem arises, if you give just an enumeration as a string (1, 2, 3), then, which is logical, the query returns zero rows, but if this enumeration is first converted into an array , then I get an error at the output: Array to string conversion
Obviously, he wants to see a string, not an array, but it's not clear how to solve this problem.
I would appreciate any advice.
