Placing two venn diagrams on one chart

Question

Using VennDiagram package I'm generating two graphs in the following manner:

# First graph
VennDiagram::draw.pairwise.venn(
    area1 = 100,
    area2 = 70,
    cross.area = 30,
    category = c("A1", "B1"),
    fill = c("#00204DFF", "#FFEA46FF")
) -> vg1

# Second graph
VennDiagram::draw.pairwise.venn(
    area1 = 120,
    area2 = 80,
    cross.area = 10,
    category = c("A2", "B2"),
    fill = c("#000004FF", "#FCFFA4FF")
) -> vg2

When called via grid::grid.draw(vg1) and grid::grid.draw(vg2) the charts show as expected:

grid::grid.draw(vg1)

grid::grid.draw(vg2)

Question

How can I create one grid object where both plots are placed one under another?

Attempt

grdFrme <- grid::grid.frame(name = "gf")
grid::grid.pack("gf", vg1)

Error in packGrob(grid.get(gPath), grob, side, row, row.before, row.after, : invalid 'grob'

Desired results

One solution could be to use awesome multipanelfigure package (fill the panels with base, 'lattice', 'ggplot2' and 'ComplexHeatmap' plots, grobs, and PNG, JPEG, SVG and TIFF images).

library(multipanelfigure)
figure <- multi_panel_figure(columns = 1, rows = 2)

figure %<>% 
    fill_panel(vg1) %<>%
    fill_panel(vg2)
