Hello J. and all,

See some new enhancements [on V1.2022.6beta] about this topic, here:

• https://forum.plantuml.net/14145/plantuml-draw-odd-line?show=15981#c15981

Here is a first proposal (Thank to PlantUML team):

@startuml
participant Alice as A
participant Bob  as B
participant Charlie  as C

A -> B  : usual request
A <-- B : usual response

note over B, C : this shows a delay in transmission

B ->(25) C : non-instantaneous message
@enduml

If that can help,
Regards.
