Plutus -- Event sourcing inquiry ( using event logging coupled with query/pub-sub to drive interaction between onchain and offchain code

Just finished Plutus Pioneer Week01 on youtube, curious if there is a event log support that can be queried to drive interactions between on-chain and off-chain code.

For example, suppose in the Plutus Pioneer Week01 bidding example the off-chain code was “listening” to bid events and popped up a notification to those participating in the bid so they know they need to take some action ( increase bid ) or not.

If so where does one find documentation for this functionality.

Sorry in advance if this is covered later in the Plutus Pioneer course and thanks in advance for any support or guidance.
