This paper is an addendum to the paper, published in Bulletin of Taras Shevchenko National University of Kyiv (Series: Physics & Mathematics), 2022, No. 3, pp. 42-44.

In the original version does not given a clear definition of the corepresentation of an algebra with identity what led to some formal inaccuracies (regarding notations, writing of defining relations, etc.). All the results of the original paper are essentially correct, but an error was made in the last part of the proof of Theorem 1, which does not affect the correctness of the idea of proof, but requires extended considerations.

In this addendum the author provides detailed information on everything related to statements about the generating elements and defining relations of the Munn algebras over algebras with identity.
