disabled field with appended button not disabled

[matxx]

Hi,

I'm trying to append a link to a field (the link depends on the value of the field).
That field can be disabled but I'd like that button to work (i.e. not being disabled) even if the main field is disabled.

I can't find a way to make it work

here's a playground to try it out :
