Hello,
The hyperlinks for Actors don't work in use case diagrams, have a look at this example :
@startuml
title Meeting
actor :Test [[
https://www.google.com Squad]]: as Squad
:Test [[
https://www.google.com PO]]: as PO
usecase RP as "[[
https://www.google.com Release planning]]"
PO --> RP : "[[
https://www.google.com leads]]"
Squad --> RP
@enduml
but this one is perfectly working :
@startuml
title Meeting
actor :Test Squad: as Squad
:Test PO: as PO
usecase RP as "[[
https://www.google.com Release planning]]"
PO --> RP : "[[
https://www.google.com leads]]"
Squad --> RP
@enduml
Thanks a lot
