should_block hook does not work

[silvarc141]

To Reproduce Config:

-- buffer opens in a tab so config loads
window = { 
  open = "tab",
},
-- works properly, otherwise has no effect on the issue
-- block_for = {
--   gitcommit = true,
--   gitrebase = true,
--   nu = true,
-- },
hooks = {
  -- does not work: true, false, not set - same result
  should_block = function(argv) return true end
  -- should_block = function(argv) return false end
}

Expected behavior should_block hook determines when host should be blocked

Desktop (please complete the following information):

• NixOS
• alacritty, neovide
• NVIM v0.10.2

Additional context Initially started with the second config from the README, tried to narrow it down
