Does the third link contain material that has been approved?
I am not sure if this is the same book but the “pieta book” was condemned

Clear as mud. It seems the EWTN link is condemning a different booklet, not the Pieta.
The link you provide says:
Here is the text condemning the booklet: A Monitum from the Holy Office: In certain places a booklet has appeared with the title “The Secret of Happiness: Fifteen Prayers Revealed by Our Lord to Saint Brigid in the Church of Saint Paul in Rome,” published in various languages at Nice (and elsewhere).
Since it is asserted in this booklet that certain promises were made by God to Saint Brigid, and it is by no means certain that these promises were of supernatural origin, Ordinaries of places [bishops of dioceses] must avoid giving permission to publish or to reprint works or writings which contain the aforesaid promises.
Given at Rome, from the Holy Office, 28 January, 1954
(Acta Apostolicae Sedis 46-64, as contained in Canon Law Digest, Vol. IV, p. 389, Milwaukee: Bruce Publishing Company, 1958)
Anything published in the Acta Apostolicae Sedis is official and binding.
Here is what the online pieta booklet says:
These prayers were revealed by Our Lord to Saint Bridget in the Church of St. Paul at Rome, and are published under sanction of the Decree of November 18, 1966, published in the Acta of Apostolicae Sedis, Vol. 58, No. 16 of December 29, 1966.
The prayers have been approved by Pope Pius IX, and Pope Benedict XV expressed himself as follows on the Revelations of St. Bridget:
“The approbation of such revelations implies nothing more than, after mature examination, it is permissible to publish them for the unit of the faithful. Though they don’t merit the same credence as the truths of religion, one can, however, believe them out of human faith, conforming to the rules of prudence by which they are probable, and supported by sufficient motives that one might believe in them piously.”
