 Here is an example of how to use `filters`, where the key corresponds to the event variable name:
 
-```
+```javascript
 useScaffoldEventHistory({
   contractName: "YourContract",
   eventName: "contracts::YourContract::YourContract::GreetingChanged",
   fromBlock: 0n,

 1. Filter Keys: The keys in the `filters` object must correspond to event fields annotated with `#[key]`.
 2. Filter Values: The value of a filter can be an array, meaning the event value can match any element in the array. For example:
 
-```
+```javascript
 {
   setter: [
     "0x00daC9BCF0bC21a9f3483D47A8Ade4764EE5c0377B3bCDDf2df477E3C1e55810",

 3. Handling Variable-Length Event Keys: For events with variable-length keys annotated with #[key], such as new_greeting in the GreetingChanged event:
 
-```
