@andrewkroh @marc-gr can you confirm where we're at with this integration? It goes back to July, so hoping to get the review complete or get any changes required by Crest done ASAP. Thanks!

last week we merged the required fix for the pagination to work (elastic/beats#33400), just waiting for a confirmation that it works for them and overall that would be it

[andrewkroh]

From talking with @vinit-elastic there is one more issue found while testing the latest snapshot that affects the page number state. They will open a new issue for elastic/beats to track the problem and link it to the related integrations PRs.
