litedb database file size keeps increasing although deleting data

Question

There are two applications,

• one console application keeps writing data to a litedb database continuously.
• The other console application reads data and deletes whatever was read

var liteCollection = _liteDb.GetCollection<SomeClass>("ColName");

var data = liteCollection.FindAll().ToList();

//prepare list if id's and delete
var ids = data .Select(l => l.Id).ToList();
var count = liteCollection.DeleteMany(rp => ids.Contains(rp.Id));

Everything looks great, but the database file size keeps growing and is not reducing at all. How to shrink the database?

I get to know some shrink command, but how to use it? A liteDb.Shrink() option I am not seeing and is not available.

• Is there any API available to shrink the database and how to use it?
• The above read and delete code I am running in loops which call every 5 minutes, can I use Shrink as well right after delete?
• Is my predicate right for DeleteMany or is there another way to do this as well?
