I have experience with mouse movements and clicks. So built-in mechanics are not working in this VM. The mouse moves, but the VM does not respond to that action, e.g. some hover action should be triggered and clicks did not work.

And I ended up with using shell CLI cliclick app and use it directly. Probably, HS has some common issue with emulating that does not in VMs.

Code

-- Function to simulate mouse click at specific coordinates using cliclick
local function clickAt(x, y)
    hs.execute(string.format("/opt/homebrew/bin/cliclick c:%d,%d", tonumber(x), tonumber(y)))
end

-- Function to simulate mouse movement using cliclick
local function moveMouse(x, y)
    hs.execute(string.format("/opt/homebrew/bin/cliclick m:%d,%d", tonumber(x), tonumber(y)))
    hs.execute('sleep 0.25')
end
