Today scan-action automatically creates new alerts in GH Code Scanning Alerts but as packages get auto fixed these alerts stick around.

1. Can scan-action look for alerts it "created" and close them when it can be determined they are fixed (i.e. package 1.2 has an error but the project now uses 1.3 - so dismiss the alert since it is stale/fixed)

According to this 3 years old issue #142 then it's even worse, because dismissing these alerts will not help as scan-action will re-open them. I have yet to confirm this.

2. Can scan-action keep track of alerts it "created" but has been dismissed and not create new ones / reopen them as they should be considered muted ?

Maybe people have moved on to more useful code scanning tools that integrate better with GH? Any tips are welcome!
