I want to execute certain events when the user clicks on the accept action. Is there a similar example?

    private fun openDiffWindowInEditor(
        file1: String,//new file
        file2: String,//old
        toolCallId: String,
        isNewFile: Boolean
    ) {

        val editorManager = FileEditorManager.getInstance(project)
        val openFiles = editorManager.openFiles.filterIsInstance<ChainDiffVirtualFile>()
        if(openFiles.isNotEmpty()){
            ApplicationManager.getApplication().invokeLater {
                openFiles.forEach {
                    editorManager.closeFile(it)
                }
            }
        }

        val newFile = File(URI(file1))
        val nf = runBlocking(Dispatchers.IO) {
            LocalFileSystem.getInstance().refreshAndFindFileByIoFile(newFile)
        }
        if(nf!=null){
            VfsUtil.markDirtyAndRefresh(true, false, false, newFile)
            val of = LightVirtualFile("Diff",file2)
            val content1: DiffContent = DiffContentFactory.getInstance().create(project,nf)
            val content2: DiffContent = DiffContentFactory.getInstance().create(project,of)
            val diffRequest = SimpleDiffRequest(newFile.name, content2, content1, newFile.name, newFile.absolutePath)
            diffRequest.putUserData(DIFF_TOOL_KEY, toolCallId)
            diffRequest.putUserData(DIFF_PROJECT, project)
            diffRequest.putUserData(DIFF_NEW_FILE, newFile)
            diffRequest.putUserData(DIFF_OLD_FILE, of)
            diffRequest.putUserData(DIFF_IS_NEW_FILE, isNewFile)
            ApplicationManager.getApplication().invokeLater {
                DiffManager.getInstance().showDiff(project, diffRequest)
            }
        }
    }
