Add a new custom actions group to Site Settings in O365

Question

I need to add a new Custom Actions Group to Site Settings page and inside this group a new custom link.

On the click of this custom link the user should be redirected to the Provider Hosted App that I have created.

Is this achievable in O365? If Yes, then how can this be implemented?

Please refer the screen shot below to understand where I want to add the new group and link. I hope that will make my question clear.

Try using this code for adding custom action to the site settings page.

// Add site settings link
UserCustomAction siteSettingLink = clientContext.Web.UserCustomActions.Add();
siteSettingLink.Group = "SiteTasks";
siteSettingLink.Location = "Microsoft.SharePoint.SiteSettings";
siteSettingLink.Name = "Sample_CustomSiteSetting";
siteSettingLink.Sequence = 1000;
siteSettingLink.Url = string.Format(DeployManager.appUrl, clientContext.Url);
siteSettingLink.Title = "Modify Site Metadata";
siteSettingLink.Update();
clientContext.ExecuteQuery();

And to add site actions link

//Add site actions link
UserCustomAction siteAction = clientContext.Web.UserCustomActions.Add();
siteAction.Group = "SiteActions";
siteAction.Location = "Microsoft.SharePoint.StandardMenu";
siteAction.Name = "Sample_CustomAction";
siteAction.Sequence = 1000;
siteAction.Url = string.Format(DeployManager.appUrl, clientContext.Url); ;
siteAction.Title = "Modify Site Metadata";
siteAction.Update();
clientContext.ExecuteQuery();
