Sounds simple, but these are actually hard cases for Flic. Using the hub is quite a limiting factor, as is executing commands on PC coming from cloud. Using the flic hub, you cannot achieve this without creating some external actions.
There are some utilities for Windows that have been designed for this. For example TRIGGERcmd has quite a simple setup with ready made IFTTT applet you could use, I think more advanced and requiring a bit more setup would be AssistantComputerControl; it might overall be a better solution if you have other smart home devices.
For the phone it's enough that you download and "always run" IFTTT app there.
