Jira or Confluence is affected by Adobe Flash?

[kim hanbyul]

Adobe says Flash Player support is about to end.(2021/01)
Is there a function related to Adobe Flash in the Jira and Confluence except add-ons?
I'm worried.
The version currently used is as follows.

Jira : v7.12.0
Confluence : v6.14.3

Flash was used a long time ago to display certain file types but was replaced with HTML5.  Both of the versions you listed do not use flash player unless you have an app (add-on) that uses it.  Is there a certain reason you are concerned?  Do you have pages or issues with flash on them?

Thank you for the Response, Brant. 
There is no other problem.
I've never used  Jira  and Confluence.
So I have a lot of questions.
Have a good day.
