TYPO3 9.5: Replace RealURL-code with Advanced Routing Configuration - typo3

Question

How do I get this code from RealURL into the TYPO3 9.5 'Advanced Routing Configuration'?
With 'aspects' type 'PersistedAliasMapper', you can only map to the UID.
But I want to map to another field!
In my case over the 'event_id' field.
array(
'GETvar' => 'tx_extension_search[eventid]',
'lookUpTable' => array(
'table' => 'tx_extension_domain_model_event',
'id_field' => 'event_id',
'alias_field' => 'title_alias',
'useUniqueCache' => 0,
'useUniqueCache_conf' => array(
'strtolower' => 1,
'spaceCharacter' => '-'
)
),
),

I would suggest to add a slug field. With this the editor can handle the url segment of every record.
Here are the needed changes:
SQL:
CREATE TABLE tx_extension_domain_model_event (
slug varchar(1024) DEFAULT '' NOT NULL
);
TCA of tx_extension_domain_model_event
'slug' => [
'exclude' => true,
'label' => 'LLL:EXT:core/Resources/Private/Language/locallang_tca.xlf:pages.slug',
'config' => [
'type' => 'slug',
'size' => 50,
'generatorOptions' => [
'fields' => ['title'],
'replacements' => [
'/' => '-'
],
],
'fallbackCharacter' => '-',
'default' => ''
]
],
The configuration in your config.yaml, with e.g. showAction to show the details of an event:
routeEnhancers:
YourPlugin:
type: Extbase
extension: ExtensionKey
plugin: Search
limitToPages: [Put your detailPagePid here]
routes:
- { routePath: '/event/{event}', _controller: 'Event::show', _arguments: {'event': 'event'}}
defaultController: 'Event::show'
aspects:
event:
type: PersistedAliasMapper
tableName: 'tx_extension_domain_model_event'
routeFieldName: 'slug'
