How to continue a stopped animation_timeline?

Description

I created an Animation timeline, According to the API, the animation can be stopped, but there is no corresponding API to continue the animation. How can I achieve this?

What MCU/Processor/Board and compiler are you using?

What LVGL version are you using?

LVGL 8.3.2

What do you want to achieve?

stop and continue the animation timeline.

What have you tried so far?

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

void anim_timeline_create(void)
{
		lv_anim_t a;
		lv_anim_init(&a);
		lv_anim_set_exec_cb(&a, (lv_anim_exec_xcb_t) lv_obj_set_height);
		lv_anim_set_var(&a, guider_ui.coffeePour_img_empty);
		lv_anim_set_time(&a, 3000);
		lv_anim_set_repeat_count(&a, LV_ANIM_REPEAT_INFINITE);
		lv_anim_set_values(&a, 74, 0);

		/* Create anim timeline */
    	anim_timeline = lv_anim_timeline_create();
		lv_anim_timeline_add(anim_timeline, 0, &a);
}

void start_function(void) {
		if(!anim_timeline) {
		    anim_timeline_create();
		}
		lv_anim_timeline_start(anim_timeline);
}

void stop_function(void) {
		if(anim_timeline) {
		    lv_anim_timeline_stop(anim_timeline);
		}
}


void continue_function(void) {
         .......
/* How to achieve ?*/

}
