@Dammit pretty much, it is labour intensive repairing and building up in layers, eight hours for a passenger seat and 1.5 hours a rear side bolster.
1/ wash seats and dry
2/ clean with leather cleaning solvent
3/ fill cracks or damage with leather filler paste and dry gently with heat gun, rub down with mild scotch brite pad, repeat 2/ & 3/ until happy with finish.
4/ apply layer of leather colour with sponge pad or spray gun
5/ dry and rub down and repeat until happy with finish {don't rub down finish top coat
6/ there are some colour fixer treatments to protect it.

Not to come across as rude, but you should mention who supplied the kit you used again ;)
I've used the woolies kits (https://www.woolies-trim.co.uk/category/117/leather-renovation) on older leather, and used fine wire wool to clean the leather. Used a paint pad to paint the leather. It is very labour intensive.

On a practical note. How do people clean / freshen up the leather contact points in the car?
Ours have taken a fucking battering over the last two years from our covid antibac routine.
