Mongoose - MongoError: Unrecognized pipeline stage name: '$eq'

When I run the following Mongoose aggregate query, I get an error:

Query:

await Users.aggregate([
    { $eq: ["$bot", false] }
]);

Error:

MongoError: Unrecognized pipeline stage name: '$eq'

    at _combinedTickCallback (internal/process/next_tick.js:131:7)
    at process._tickDomainCallback (internal/process/next_tick.js:218:9)

Am I using it wrong?
