Excellent point but it makes it even more confusing to ask God to approve it.
It shouldn’t. The epiklesis is asking God to make the bread and wine acceptable, for the Holy Spirit to bless them to make them worthy to be transubstantiated (remember, the epiklesis happens before the words of institution):
Be pleased, O God, we pray,
to bless, acknowledge,
and approve this offering in every respect;
make it spiritual and acceptable,
so that it
may become for us
the Body and Blood of your most beloved Son,
our Lord Jesus Christ.
On the other hand, the actual oblation of the Body and Blood occur during the Supra quae propitio and Supplices te rogamus prayers (within the Canon):
Be pleased to look upon these offerings
with a serene and kindly countenance,
and to accept them,
as once you were pleased to accept
the gifts of your servant Abel the just,
the sacrifice of Abraham, our father in faith,
and the offering of your high priest Melchizedek,
a holy sacrifice, a spotless victim.
and:
In humble prayer we ask you, almighty God:
command that these gifts be borne
by the hands of your holy Angel
to your altar on high
in the sight of your divine majesty,
so that all of us, who through this participation at the altar
receive the most holy Body and Blood of your Son,
Those happen AFTER the words of Institution. So the priest is speaking about the Body and Blood of Christ. To me, the Supplices te rogamus prayer really shows, better than anything else in the canon, how heaven comes down to the Sanctuary during the Eucharistic Prayer. It shows the eternal nature of the Sacrifice.
