use same counter (shared counter) for multiple schemas

[jpolvora]

Suppose I have 2 schemas:

let sch1 = new Schema({
    _id: Number
})

let  sch2 = new Schema({
    _id: Number
})

I need to use same counter (same sequence) for both schemas

So, I expected to write the following code:

sch1.Plugin(AutoIncrement, {id: 'mySharedCounter'})
sch2.Plugin(AutoIncrement, {id: 'mySharedCounter'})

But the program crashes with the following error

Counter already defined for field "mySharedCounter"
at Sequence.getInstance (D:\PROJECTS\golden\node_modules\mongoose-sequence\lib\sequence.js:69:15)
at Schema.plugin (D:\PROJECTS\golden\node_modules\mongoose\lib\schema.js:1198:3)

Not sure but I believe that the behavior should be: "If the counter already exists, use that counter". Or maybe create a new option (perhaps useSharedCounter: true //default false
So the library not throw error if there's already a counter with same name if useSharedCounter=true

Then I write the following code:

sch1.Plugin(AutoIncrement, {id: 'mySharedCounter', useSharedCounter: true})
sch2.Plugin(AutoIncrement, {id: 'mySharedCounter', useSharedCounter: true})
