R 如何使用包metaviz更改标签的小数位数

我正在使用"metaviz"包来显示几个不同研究的结果.更具体地说，我正在使用viz_Forest函数创建一个森林图，我希望在图的右侧显示带有配置项的估计值.但是，它会自动四舍五入到小数点后第二位，我希望它四舍五入到小数点后第三位.

viz_forest(x = dfamce_ordered[1:20, c("amce", "std")],
           study_labels = dfamce_ordered[1:20, c("country")],
           summary_label = "Summary Effect", 
           xlab = "AMCE", 
           annotate_CI = TRUE)

Data:
