Changing signature watermark on Acrobat, MacOS

I managed to do it on my Windows PC following Custom Signature Appearances — Digital Signatures Guide for IT, but not with so much luck on my Sillicon MacBook.

Apparently, as opposed to Windows, there is no Security folder at located at /Users/(user name)/Library/Application Support\Adobe/Acrobat/(version)/Security.

My folder structure is as follows:

/Library/Application Support/Adobe/

/Library/Application Support/Adobe/Reader/DC

/Library/Application Support/Adobe/Acrobat/DC/

Creating /Security/ in any of these and adding SignatureLogo.pdf does not change the Adobe watermark to my logo. Adding SignatureLogo.pdf into any of the parent folders does not change it either.

Something to note is that there are no acrodata files in any of these locations, which leads me to think they might be somewhere else or not exist at all.

Has anyone updated their signature in more recent versions of Acrobat and MacOS and knows the new location?
