Simple Script, Removing a single achievement?

Need some help for a script on removing a SINGLE achievement. I know the code for removing all the achievements which is (not mine):

if managers.achievment then
for id,_ in pairs(managers.achievment.achievments) do
if managers.achievment:get_info( id ).awarded then
managers.achievment:clear_steam(id)
end
end
end



It just does a for loop through every id and then performs clear_steam(id) on each.

Where can I obtain the individual achievement ID's?

What if I want to remove a single suspicious achievement only?

Thanks,

Use achievement manager/unlocker, you can choose specific achievements to unlock/lock
