Query to fetch assets with either offTime doesn't exists or offTime greater than current time.

Please see my query below.

p.limit=-1
p.offset=0
path=/content/dam
type=dam:Asset

1_property=jcr:content/cq:lastReplicationAction_scene7
1_property.value=Activate

2_property=jcr:content/cq:lastReplicationAction
2_property.value=Activate

3_group.or=true

3_group.1_property=jcr:content/metadata/custom:assetType

3_group.1_property.1_value=image

3_group.1_property.2_value=document

3_group.1_property.1.operation=equals

3_group.1_property.2.operation=equals

4_group.or=true

4_group.1_property.operation=not

4_group.1_property=jcr:content/offTime

4_group.2_daterange.property=jcr:content/offTime

4_group.2_daterange.operation=>=

4_group.2_daterange.lowerBound=1729147820649

orderby.sort=asc

orderby=@jcr:content/jcr:lastModified



The corresponding XPath generated is,

/jcr:root/content/dam//element(*, dam:Asset)
[
((jcr:content/metadata/@custom:assetType = 'document' or jcr:content/metadata/@custom:assetType = 'image'))
and (not(jcr:content/@8690475)
and (jcr:content/@8690475 > xs:dateTime('2024-10-17T06:50:20.649Z')))
and (jcr:content/@5644378:lastReplicationAction_scene7 = 'Activate' and jcr:content/@5644378:lastReplicationAction = 'Activate')
]
order by jcr:content/@6655266:lastModified

But what I'm looking is those assets where the offTime doesn't exist or offTime greater than current time, which should be an OR condition. But what I'm getting is an AND condition. How do I solve this?
