Backlinks to GMB ?

Good morning friends...
I'm looking for TRUE information about creating backlinks to GMB.
Do you have any real experience?
What type of backlinks are used for this strategy?
I looked online for information but there are many conflicting opinions...
Logically I cannot insert other "NAP citations" as they have already been linked to my site. Thank you

Backlinks to a GMB listing aren't the same as to a website. Focus on local citations and NAP consistency across directories—that's your bread and butter for GMB.

I've done some tests on this. I sent GSA blasts to various URLs of the GMB. It does diddly squat. Nothing.

I've also done Map Embeds on Web 2.0's and indexed those. Nothing.
