Install and reinstall action

Webhooks and Events
1

I am building an app using the Remix template and want to perform a few backend actions when the app is installed or reinstalled. Where do I add these code blocks since there is no webhook like shopify app uninstall for installation or reinstallation.

for the uninstall you can use webhook （app/uninstalled）
For the install and reinstall，you can do the business logic after auth.
