how to declare mongoose static methods that will work with ESLint

Using Mongoose ORM for MongoDB

I've declared a mongoose static method like:

ConvoDataSchema.statics.randomItem = async function () {
const ConvoData = mongoose.model('ConvoData', ConvoDataSchema)

but later when I want to call it:

let convoData = await ConvoData.randomItem()

My linter is not aware that ConvoData has had this magical method patched onto it by Mongoose.

How can I declare these methods such that a Linter (TSLint / VSCode Intellisense) can properly discover these methods?
