Importing Custom Invoice Templates into QuickBooks Online

New user to QBO and somewhat perplexed by the inability to create or match existing company brand to a professional level within QBO. Found an old article created in 2018 which illustrates a level of flexibility to create a word template and import directly into QBO as an invoice template but this feature appear to have been removed in 2021 - Why?

If there is no longer a solution to create professional stationery items this would mean IMHO QBO is not fit for purpose for brand conscious organisations
