It it is a slight shocking feeling, it is a common issue with many laptop. It is a floating ground issue. It is not harmful and if you want can be fixed by using an Apple grounded cable. In the US this is the one. https://www.apple.com/shop/product/MK122LL/A/power-adapter-extension-cable?afid=p238|sez9guAow-dc_mtid_1870765e38482_pcrid_246386725857_pgrid_14874603490_&cid=aos-us-kwgo-pla-btb--slid---product-MK122LL/A

Been reported and discussed at least a few times on MR. Nothing to worry about.
