How to add custom action group in list settings page?

Question

I want to add one custom action in my custom group in list settings page. I have done following for that
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<CustomActionGroup
Id="LibrarySettings.MyGroup"
Title ="My Group"
Sequence="1000"
Location="Microsoft.SharePoint.ListEdit">
</CustomActionGroup>
<CustomAction Id="Custom.Configuration.ListCustomSettings"
GroupId="LibrarySettings.MyGroup"
Location="Microsoft.SharePoint.ListEdit"
RequireSiteAdministrator="FALSE"
Sequence="100"
Title="Library Admins">
<UrlAction Url="_layouts/15/LibrarySettings.aspx?List={ListId}" />
</CustomAction>
</Elements>
But custom group is not created in list settings
Any idea what I am missing here?

Hi,
Per my understanding, you might want to add a custom action group into the list settings page.
In the same way, we can add custom group into “Site Settings” page(C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\settings.aspx) by specifying
the Location attribute to "Microsoft.SharePoint.SiteSettings".
However, in the “List Settings” page(C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\listedit.aspx), the three groups “General Settings”,
“Permissions and Management” and “Communications” are hardcoded there which occupy all the space, it is by design.
As a workaround, you can modify the HTML source code of the “listedit.aspx” to generate a custom group there manually.
