How to Assign a Custom Shard Key Value to a MongoDB Zone?

How can I add a range to a zone where the value is limited to only one ObjectId?
In other words, the minimum parameter and the maximum parameter should both be an ObjectId.

For example :

sh.addTagRange("mydb.mycollection", { "_id": "6512ca368177c2ceeb0ae24a" }, { "_id": "6512ca368177c2ceeb0ae24a" }, "Z1");
