Custom event instrumentation for PostHog

[iskyOS]

I'd like to set up custom event capture for our website using PostHog. Here is the guide on how to do so: https://posthog.com/tutorials/event-tracking-guide

Can you please look into this and help with instrumentation to capture these events? Here is full documentation on the events that we would like to capture: https://docs.google.com/document/d/1Ibhh6TAy--HipKBwd5DL-sooqo5rWAymvM5fWZcz7F4/edit

I can also create a PostHog account for GitStart using your preferred email.
