Hello - how to enable this rule? <https://github.com/detekt/detekt/blob/cb29e0a71d3f27134b769dfad296e7307c013242/detekt-formatting/src/main/kotlin/io/gitlab/arturbosch/detekt/formatting/wrappers/TrailingComma.kt|https://github.com/detekt/detekt/blob/cb29e0a71d3f27134b769dfad296e7307c013242/det[…]o/gitlab/arturbosch/detekt/formatting/wrappers/TrailingComma.kt>

Hello, I haven't tried but maybe this will be helpful:
<https://github.com/detekt/detekt/blob/main/detekt-formatting/src/main/resources/config/config.yml#L182>

Have you imported the detekt formatting plugin?

Thx I was able to <https://github.com/igorwojda/android-showcase/commit/31f51c186c56fd84362c1a452befc3d77e6aedd9|make it work>.

It looks like my default detekt config didn't have any rules from the above `detekt-formating` rule set. I added this manually and it had worked.

<@U0GDW9ZK4> is there a detekt check to make sure that custom config file contains all of the rules? (kid of detekt config meta check)
As you see it is easy to miss `detekt-formating` rule set ot upgrade detekt without updating config files (thus config for some rules will stay kind of hidden)

BTW There may be also potential improvement for the documentation as it was not obvious how to enable these rule with custom config (I would expect to have some info here <https://detekt.dev/docs/rules/formatting>)

Thanks for the hint! May I ask you to submit your ideas via GitHub issues?
