"Eagle Eye - Recently Viewed Products" app - leftover code removal issues

[MikiSpace]

I have been using the Eagle Eye - Recently Viewed Products app for some time now, but recently got a message from Shopify that the app was due to be removed from Shopify.
I uninstalled the app from my store, but the recently viewed products tab is still showing up on the webshop pages.
There must be some leftover code from the Eagle Eye - Recently Viewed Products app in the liquid.files that needs deleting I guess.
I have no idea how to find the leftover code to delete it.
Shopify support were not able to help and sent me here
Can anybody help ?
I am using Kagami Theme, (version 5.0.2)
