@KevLehman JFYI: There are some conflicts here wrt the new settings interfaces which the team has recently introduced. More details about the change over here 😬

[murtaza98]

Recommending some cleanup tasks since we now no longer need estimatedInactivityCloseTimeAt property on inquiry docs.

We won't need these 2 methods anymore

• setEstimatedInactivityCloseTime
• unsetEstimatedInactivityCloseTime

We can also remove this property from the search filter from here

Verified and tested this PR and functionality wise it is working properly 🚀 . So once the merge conflicts are resolved, I think we'll be in good shape to merge it 🎉

Tested the functionality of the fix and it works, good one @KevLehman, i learned a lot from this PR.

edit: one thing i found was that the Livechat_max_queue_wait_time setting is disabled on the frontend, had to edit the HTML for it to work.
