If the Delay is part of a Group, it will be named here.
A Group can also be part of another Group, thus, a Group name will be the concatenation of all nested Group names: group1::group2::..::group3 (here, group3 being the deepest one).
When Fixed Time is selected, as soon as the specified time is elapsed, the Delay triggers.
For i.e: if the Delay is inside a Logic with a Fixed Time set to 10 seconds. If the Logic is triggered 1 minute after the simulation start, then the Delay will be triggered 1 minute 10 seconds after the simulation start.
A random value (according to the Distribution) will be taken at Delay initialization. This random value between Min and Max values will act as Fixed Time.
