Filler plug Gearbox/chain.

[Seán1959]

I mistakenly undone the drain plug for the gearbox/chain near the engine oil drain plug. About 200 mil of amber oil came out. Can anybody please supply a drawing or advice about where the filler plug is? I do believe there's a workaround to make it a little easier to get to so I can refill it BMW C650 GT 2016. Thanks
