                            icon="send"
                        />
                    </template>
                </q-input>

You can add classes flex items-end to your q-input to move the send button down.

Add this additional css to move the cancel button to the bottom. Caution: you probably need to make the selector more specific or scope it to the current component to not affect other elements.

.my-input .q-field_append {
  align-self: flex-end;
}
