PDF embded alignment

Great plugin, I appreciate all the work that went into it and the funcionality it adds.
I'm using Joomla v4.2.3 with the pdf-embed-v3-0-0-e3024fbe-zip package
Having trouble getting the document display to align with the left margin of the parent window.
The full width of the document will show, if I move the slider all the way to the right.
Same behavior with different browsers, different viewers (google, adobe & pdfjs) and different
height and width specifications
{pdf=https://site.com/images/qe/docs/BoardMinutes_20220929.pdf|500|300|pdfjs}
{pdf=https://site.com/images/qe/docs/BoardMinutes_20220929.pdf|100%|100%|pdfjs}
The left margin of the document displays more than halfway past the middle of the module position
This occurs in the Cassiopia main-top module position

Any ideas to move to the left would be appreciated.
Thanks!
