Historicity of the last supper in 1 Corinthians 11:23-26

According to the scholar Robyn Faith Walsh in this article (https://www.religiousstudiesproject.com/response/a-jesus-before-paul/):
The ahistorical nature of our traditional social models is evident in scholarly discussion about Paul’s quoting of Jesus. While there are several examples, allow me to focus on what is traditionally called the Last Supper. In 1 Cor 11:23-25, Paul details the events “on the night [Jesus] was betrayed,” including his words as he broke bread and offered wine as a “new covenant.” This same description of events—and nearly the same wording—also appears in Mark 14:22-25, Matthew 26:26-29, and Luke 22:15-20. One common argument against the idea that the gospel writers could have been using Paul to inform this passage is that, when quoting Jesus, Paul frequently discloses that he has received these sayings “from the Lord” directly. In other words, Paul indicates that he is receiving these commands through some form of divination. He does not attribute these sayings to any other authority in a position to have spoken directly to Jesus or to have been present at the events described (e.g., James or Peter). In short, scholarship has tended to gloss over the significance of Paul’s claims that he is, evidently, receiving privileged intel from the risen Christ. Indeed, Paul is clear that his knowledge of this event and Jesus’ words is supernatural: “For I received from the Lord (γὰρ παρέλαβον ἀπὸ τοῦ κυρίου)…” (1 Cor 11:23). Here Paul utilizes language found elsewhere in his letters (e.g., Galatians 1:12) to indicate his knowledge is via “revelation” (xἀποκαλύψεως) and “neither from another human being, nor was I taught (οὐδὲ γὰρ ἐγὼ παρὰ ἀνθρώπου παρέλαβον αὐτό, οὔτε ἐδιδάχθην).”
