Payment Trust Icons / Quality Seal Badges + Sales Urgency Creation tools

New to this forum and infact first time recording my presence here with a request.
I have Wordpress/ woocommerce based website and i want to improve/ optimize my Product page & Cart checkout page by introducing
(A) Payment Trust Icons + Quality Seal Badge below Add to Cart or Buy Now buttons and
(B) Introduce few Sale urgency creation elements (other than Sale badge/ countdown timer/ Stock display) - For example : X orders in last 7 days, Only x units remaining. Selling out fast, you save $X (10%).
I use elementor page builder and have very limited coding knowledge.

Can you guys suggest some plugin (free or cost effective) or some data source where help is available ?

Thanks in advance
