Shavuot Night Repair

Hello Rabbi
I wanted to ask what your opinion is regarding the “Shavuot Night Correction”, mainly as a follow-up to your articles that touched on the definition of “study”.
In various communities (mainly Sephardic and Hasidic) it is customary to read the “Tikkun” that was formulated by the Ari and arranged by the Chida.
On the one hand, the matter of being awake at night is essentially a Kabbalistic idea (its initial source is in the Zohar), all that is reasonable to say is that whoever maintains the base because of a Kabbalistic directive, it is better to fill its contents according to that directive. In other words, if you are awake at night to repair “24 bridal decorations,” you should listen to the experts on how to repair them.
On the other hand, the distribution of the “Tikkun” has spread, and today it is recited by many people who do not understand the literal meaning of the verses they are reading, even if they want to understand. In particular, in the Mishnai section of the Tikkun, anyone who seeks to understand the Mishnai presented without context and without interpretation must have extensive Torah knowledge.
In reality, people mumble verses and minhas without understanding and without concentration. It turns out that the first Kabbalistic groups included sages who knew the simplicity of things, and could also concentrate and memorize in this way. Is the reading of people who do not have this ability valuable?
Perhaps a distinction should be made between reciting verses from the Bible that have “textual sanctity,” as you say, and Mishnah, whose sanctity is only in their content?
