when I press on context selection, it does not trigger picker selection

what am I missing?

here is my minimal.lua

Default mapping was changed from <Tab> to <C-Space>

You can change it with config.mappings.complete.insert = "<Tab>"

See here for example: https://github.com/deathbeam/dotfiles/blob/master/nvim/.config/nvim/lua/config/copilot.lua#L29

thank you for quick response @deathbeam ☕

[novrian]

it seems, the default mapping is not mapped correctly.
I don't know whether this is an issue or not

for now, manual key mapping is working. thanks @deathbeam ☕

[deathbeam]

Glad to hear that. and odd about the i can def see it:

:map for some reason do not shows it but :map do not shows any isner bindings at all looks like, this is via fzf_lua keymaps
