please make all created methods return the object of ApiService and all old methods need to set private don't we able to use createConnector() at line 60 and deleteConnector() at line 123 without clusterName? seems here we also can set a date when seek type is Timestamp. so suggest tot lease String argument Condition.visible -> Condition.enabled for seekTypeFLd seems this method is not used in tests, it should be private and w/o Step annotation Condition.visible -> Condition.enabled Condition.visible -> Condition.enabled done sure ,done it  done done
 done done done
[e2e]Checking messages filtering by Timestamp within Messages/Topic
Autotest implementation for:

https://app.qase.io/case/KAFKAUI-16

Description:
Checking messages filtering by Timestamp within Messages/Topic

Pre-conditions:
- Login to Kafka-ui application
- Open the 'Local' section
- Select the 'Topics'
- Open the Topic profile
- Turn to Messages tab

Steps:
1. Change the Offset dropdown value to 'Timestamp'
2. Click on 'Select Timestamp'
3. Choose the date and time within opened calendar
**Expected result:**
All the messages created from the selected time should filtered
