Continue Reading not translatable

Hi, I have Resort Hotel Inn theme installed. In the list of blog posts, I would like to translate “Continue Reading”, however I cannot do it.

I tried:

• Loco Translate plugin – this string cannot be found there
• Downloading complete theme, and full search it for “Continue Reading”, but nothing was found
• Scanning the database, also there is no sign of this string.

I am aware of PO and MO edits, I know how to translate, however I need to find this string at first in order to translate it. Thank you very much for your help.
