Describe the bug

I have attempted to remap 'z=' to 'Ss' through vim.keymap.set('n', '<leader>'Ss, 'z=', { remap= true })

How ever when using the new key it uses the old full screen spell suggestions . Not the which key version .

I am also not sure where the mapping should be placed (I'm using lazy.nvim plugin folder structure) and if it needs to be in a particular order.

I understand that similar issues have been raised but none have solved my issue.

Any help is much appreciated

Steps To Reproduce

Add which key plugin
Add key map
Attemp to use new key

Expected Behavior

The new key would bring up the spell suggestions in the which-key format
