            let logFileUrls = self.sortedLogFilePaths.map { URL(fileURLWithPath: $0) }
            let maxLogFileCount = min(logFileUrls.count, Constants.Instabug.maxNumberOfLogFiles)
            let logFilesToAttach = logFileUrls[0..<maxLogFileCount]
            logFilesToAttach.forEach {
                report.addFileAttachment(with: $0)

            report.setUserAttribute("value2", withKey: "key2")
            // .. and few more

            if let fontSizeType = DynamicTypeSize(UITraitCollection.current.preferredContentSizeCategory) {
