Cant install smartthings

Hey all,
i had to delete the smartthings intergration and now i cant add it back in again?
it was all working fine on my current version but i was doing some clean up. im sure its not version related however
Hassio = HassOS 3.5 (using Nabu Casa)
HA = 101.2

Issue i get is shown below.
When i try and add the app in the ST app, it shows 3 different HA apps, whichever one i choose, it just “spins” and doesnt do anything.

i found something about having to delete keys. Smartthings Integration Error - Unable to setup the SmartApp. Please try again

So i installed SSH and tried to apply this: https://pypi.org/project/hass-smartthings-remove/
however i cant seem to run PIP.
so i download manually and extracted the files here: /config/custom_components/removest/hass_smartthings_remove-1.0.1#

however, is this correct? how do i execute the file?

I use the new Smartthings app on mij iPhone and can’t find out how to add the smart app under automations
