Department of Public Expenditure, Infrastructure, Public Service Reform and Digitalisation

I'm looking for a copy of any documents, but most likely email correspondence, between NAMED and NAMED that occurred around 14/12/21 in relation to 'FOI Request P190/2021'. NAMED answered a query for me on that day and implied correspondence with NAMED. - Ireland had its first Covid lockdown in Spring 2020. I'm not too sure how the State operated it with its Departments, but I'm looking documentation that shows the State's instructions to the Department of Expenditure and Reform about when its staff should start working remotely. If the Department itself decided who should and shouldn't operate remotely and when, I would like that for NAMED (I have other documentation that he had 13 days’ notice and I need to try getting that confirmed.)
