How to update jenkins plugins in installed tab

Hello Team,

How to update jenkins plugin for example we are running Nunit plugin with 0.27 version and I need to update with 0.28 version

Do I need to delete the plugin from the “installed” section and again need to install it from “available” tab? can’t we update our plugin nunit 0.28 in “installed” tab itself?

The “Updating a plugin” documentation says

Updates are listed in the Updates tab of the Plugins page and can be installed by checking the checkboxes of the desired plugin updates and clicking the Download now and install after restart button.
