#' @description This method tidies the coefficients of a bootstrapped
#'   temporal exponential random graph model estimated with the \pkg{xergm}.
#'   It simply returns the coefficients and their confidence intervals.
#'
#' @param x A [btergm::btergm()] object.
#' @param conf.level Confidence level for confidence intervals. Defaults to
#'   0.95.
