I installed some extensions manually some time ago, without composer.
Now I'd like to delete them.
Is there a way to permanently delete them?
Now they are disabled. Especially some extensions that are like "Backend Shared Extension"
I enclose some text written by the removal form guide:
Important: If you are using other WeltPixels extensions make sure not to remove the 'Backend' shared extension as is used by the rest of WeltPixel installed extensions. WeltPixel extensions it is safe to uninstall and remove also the 'Backend' extension.
