saving VBA as add-ins (xlam equivalent) for Word 2016

I created a macro that extracts the current page in a word doc and saves it as a new file. I want to save this macro as an add in like I do with excel macros but I don't know how to do so. It seems quite different than excel and google is not providing quick answers. I tried saving the file as a .dotm. I was able to add it in the add-ins box and as a button in the ribbon, but it won't allow it to be run because it cannot be found or that it is disabled due to security settings. I have checked it as a document template in the developer tab.

I read somewhere you can put your dotm file in the word parent directory to have it run automatically. the usual way I navigate to application directories is to right-click on the shortcuts on the desktop or wherever and click "open file location" but that's not working as it used to. It gets stuck in the startmenu>programs directory and doesn't take me any farther (i.e. to it's target). In the properties box, it says what it's target is "Microsoft Standard Office 2016", but not it's path. I don't recall ever having an issue with this procedure. Maybe it's because of a computer upgrade (I got a whole new faster machine plus some other versions of applications, but Windows 10 was on both). I suppose I can find the directory manually and I'll try this but I may not even be on the right track with this.

Thank for your time and help

Edit: The directory in my documents folder, Custom Office templates, where the dotm file is located is a trusted location (the normal method I use for getting around security as the office IT guy doesn't want us changing macro settings around).

Macros are commonly stored in Word's Normal template, from where they're available to all documents. If you only want a macro to be available to a certain group of documents, create a template containing the macro and attach those documents to that template (any documents created from the template will also be attached to it). You could also create your own Global template. A global template is a template (dotx or dotm file) stored in Word's Startup folder.
