[Feature request] Add support for Events in playground

[Sharaf5]

Playground is the most impressive feature you have
I would suggest adding Event based triges for it
I mean when an event hits, a flow of endpoint sequence called

Event trigers may come from

• Trigerable actions
• Timers ( or Delayed events )
  • after event
  • certain time
  • repeative
• File events
  • Create
  • Save
  • Edit
  • Typing
  • status from linter ( errors exists / passed )
• Git events
  • push
  • merge
  • release

  also for pre-events you may consider pre-commit tool integration

• Endpoint Response
  • Rest API responses
  • Graphql responses
  • Websocket massege
  • SOAP
  • cURL
  • gRPC

  if there is another you could list, but I found you really managed for websockets, so I suppose you did the same for others

• server status check
  • Ping
  • self defined checks
    • UI based
    • scripts runing
• Conditional nodes
  • If
  • Loaps
  • Find & replace
• Math nodes
  • count
  • sum
  • max / min

  you may add more

• Mixed trigers
  • combine
  • filters

you may find more things useful
