There's no such thing as a sacrament that is administered by a group ("we") to an individual. THe minister of a sacrament stands in the place of Christ. Christ is not a committee.
Neglect not the gift that is in thee, which was given thee by prophecy, with the laying on of the hands of the presbytery. (1 Timothy 4:14)
That said, I have affirmed it should be "I baptize," but as explained in my post, I do not think that "we" must invalidate the baptism of "we baptized" minister and thus (on that basis as non-convert) all the acts belonging to that office. As in https://www.firstthings.com/web-exclusives/2020/09/why-the-words-of-baptism-matter.
