Did i just find a bug in HA or PiOS when i try to access settings in HA

all im trying to do is integrate smartthings hub into HA :cry:

i cant find the configuration tab that all the online instructions talk about

I go into my HA instance (running on a Pi 4)
I go to settings
i go to home assistant cloud
I can see my Nabu Casa account is connected
i then select devices and service
i select add integration
i select smartthings
ERROR : config flow could not be loaded

what do i need to do?

NOTE: my topic for this post was because i had tried to peruse thru the HA interface 2 times prior and the system just hung. whole screen went blank. only options were if i did right click on mouse and it to then given option to add a folder . the trash icon was showing but otherwise whole screen blank. i now can not recreate it

Make sure that external_url is configured in Home Assistant. See Setup basic information - Home Assistant
