Luminous green....?
Engine & gearbox oil is normally brown to black colour.
Same with brake oil.
Coolant should be pinkish colour.
Is you AC working ok?
Power steering..?
Check all your levels , to see what's low....
Post a few pics of the levels.
And water coolant reservoir.

AC coolant is oily and can contain luminous dye to locate leaks.
Some engine coolant can be luminous green.... But the T6 normally has the pink stuff.

Oil leaks always travel down.... And back, due to the airflow.
That leak looks like it's coming from higher up and running down.
Take some more pics to see where it's coming from.
Have a feel around the cold engine to see if you can feel the area that's wet.

The bolt is supposed to be replaced after removing.... ?
Is the green definitely a pen mark?

Yes, the green is pen/ paint mark.
If all levels are good, it's possibly coming from somewhere else that you cant/not measured....
IE.
Gearbox.

I'd use some "brake clean" to clean off all that oil.
Then run the van for a day.
Then recheck the engine to see where it's leaking from.
Plan B could be to take it back to the garage that serviced it recently and ask them to have a quick look at it.

Use some water soluble degreaser and clean from the top down, rinse well and use a mirror or phone camera to find the highest oily point after running the engine.
It could be the sump plug but unlikely.
It could be the from the drive end crankshaft seal as with a similar recent case. IF this is the case it’s the gearbox and DMF out so you might want to consider replacing the clutch and DMF at this point.
The green mark has been put there by the mech as a quick reference that the plug was tightened and as a quick visual if it comes loose. Re-using a sump plug won’t result in an oil leak 99% of the time.

Most garages Inc VW now use oil extraction pumps that go in via the dip stick tube.....
So no need to remove the lower covers and sump plug etc.
But I do remember in the T5 days always being billed for a new sump plug washer every time.
Some more modern sump plugs are event plastic...!
Seem odd why the sump plug would leak,.... Either way keep us posted....

Can you check what's on the invoice for the previous service work..?
