On touch devices, the resize handle area on events is too small, making it difficult to resize.
Is there a way to increase the resize area?

You can increase the width of them using CSS

.b-sch-event::after {
    width: 13px;
}
.b-sch-event::before {
    width: 13px;
}

Hope it helps

Or set the var it uses:

.b-sch-event-resizable-true::before, .b-sch-event-resizable-true::after {
    --handle-width: 3em !important;
}

It is already upgraded to 1.7em when @media (pointer: coarse)
