Describe the issue:
There is a bug in this code line [1], where it should be fixed as here [2] which is a similar method.

[2] - https://github.com/wso2-extensions/identity-inbound-provisioning-scim2/blob/master/components/org.wso2.carbon.identity.scim2.common/src/main/java/org/wso2/carbon/identity/scim2/common/impl/SCIMUserManager.java#L2947

How to reproduce:

curl --location 'https://localhost:9443/scim2/Groups?count=1' \
--header 'Authorization: Basic YWRtaW46YWRtaW4='

Expected behavior:

The pagination support is not provided for SCIM2/Groups endpoint. But it should be possible to pass the count parameter to limit the results.
