sharepoint online – Automaticly click button when site is created

We use a SharePoint app to sign documents in our SharePoint sites. On each new site the app needs to be activated by simply clicking on two buttons. We use a lot of sites in our SharePoint environment.

Is it possible to automate this task by using some kind of a Power Automate flow that runs each time a site is created?
