I’m trying to understand if your plugin can do what it would do

hello and thanks for the plugins you develop.
I’m trying to understand if this is useful for me.

what I would like to do is

1 put all the plugins I own in a google cloud bucket / amazon bucket

2 the user or my client or me on the sites I support, I install this “updater”

3 this updater checks ALL the plugins that are installed on the site and checks if they are present in the bucket.

4 If the plugins are present, download and update them.

5 BONUS: I should insert some security check (a license key or similar to prevent anyone from activating this updater)

what did you develop do and can do these things? or you could help me understand how to make it happen.

thank you.
