We are working approach control airspace as part of a COVID-19 mitigation plan. Aircraft X was on approach to ZZZ; which is in Approach airspace; when Approach called and asked for a block for an approach in ZZZ1.  I had previously told a Controller at [another facility] that I would not be able to approve that approach because I was blocking for the aircraft into ZZZ.  When [other facility] called back and asked again for the block for ZZZ1 I again told them no.  The other Controller began to question me.  I explained the block that I needed and he still seemed confused.  I then was trying to get off the line to get back to my traffic.  I then said 'If you can keep him clear' and that I couldn't authorize the approach with my rules.  [Other facility] then said they could give him an alternate missed approach.  While I don't believe I specifically approved the approach my language may have been interpreted as authorizing the approach.  At the time I was thinking that the approach may have some procedure that I was not aware of that would allow the approach to run but upon rereading the Center SOP I do not believe that would be the case.  While I don't believe that the aircraft lost separation with each other or specifically with protected airspace they may have been on approach at the same time which is not allowed by the Center SOP.I do not believe that these approaches conflict as published and the restriction can be removed.  However; we also need more concise rules about what approaches we can and cannot run.  Our procedures were designed for the Midnight shift with low traffic and when we run the day shift we face a lot of delays because our rules are not as lenient as the approach controls that usually run the airspace.  When I have tried actually determine if these approaches conflict I keep running into problems because I am not sure who to contact and can never get concrete answers.  A central office that could evaluate the procedures; or someone in the center specifically trained in approaches who could determine whether or not they conflict would be helpful.
Center Controller also working Approach Control airspace due to the COVID-19 pandemic; reported communication issues with another Approach facility resulting in an airborne conflict.
