Need help with a quick snippet of code for the conditional formula for showing/hiding fields

hi!

i have this code and it works. When the campaign type is set to auto, this field will be visible.

=if([$CampaignType]== 'Auto', 'true', 'false')

I want to it so that if the campaign type is Auto OR Home it'll appear. I tried the below but it doesn't work.

=if([$CampaignType]== 'Auto' || 'Home', 'true', 'false')
