Questions on CV from Authors of LOR

The guideline says that " Come with the author’s CV (or other proof of their credentials that the endorsing body will accept)"
Question: Does TN accepts LinkedIn profile or an online profile from Authors of Recommendation Letters in place of CVs as other proofs of their credentials?

LinkedIn Profile is a form of CV & it is commonly used.Online profile should also work.
As long as it can let the assessor know who wrote the letter, and their background.
