how do I buckle the lillebaby carrier 😭

As

Does anyone have a Lillebaby carrier?

I am 5'2"....I'm really hoping my height isnt a factor.

But I cannot reach the strap that goes across my upper back to buckle it!

I have tried, and I cannot reach it.

I need to be able to buckle it myself.

Does anyone have any suggestions

Please and thank you 😬😬

I'm desperate to figure this out
