   * - `ssfi`: This flag stands for "start stack function indicator". It
   * contains a function reference that serves as the starting point for
   * removing frames from the stack trace of the error that's created by the
   * assertion when it fails. The goal is to provide a cleaner stack trace to
   * end users by removing Chai's internal functions. Note that it only works
   * in environments that support `Error.captureStackTrace`, and only when
   * `Chai.config.includeStack` hasn't been set to `false`.
   *
   * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
   * should retain its current value, even as assertions are chained off of
   * this object. This is usually set to `true` when creating a new assertion
   * from within another assertion. It's also temporarily set to `true` before
   * an overwritten assertion gets called by the overwriting assertion.
   *
   * - `eql`: This flag contains the deepEqual function to be used by the assertion.
   *
   * @param {unknown} obj target of the assertion
   * @param {string} [msg] (optional) custom error message
   * @param {Function} [ssfi] (optional) starting point for removing stack frames
