[Enhancement] Alert "OK" button style

[henrikvoetmand]

• I have written a good issue

Describe the enhancement

In the original Kirby design a positive action was ment to use a "Success" button. (success green button color)
But In DRB positive actions uses brand-primary color buttons (OK, Accept, Confim...)
The "Alert" component is set up to use the "Success" button, but now when we are supporting multiple brands, some PI's find this strange.

Describe the solution you'd like

Change the "OK" button in "Alerts" to use the brand-primary color. (Attention level 1 button)

Have you considered any alternatives?

No!

Are there any additional context?
