Description

What this PR does

Discussion

• Should these be defined better as lifecycle_actions or similar to allow registering actions more generally for startup (and give the option to repeat running)? If so might need to make small RFC or at least define the in-built triggers (e.g. app_start, app_minimize, app_resume, app_close, app_update etc.). Could also just be global actions or similar
