Accessibility issue with Context Menu-Confirmation needed

[innov-richa76]

Describe the bug
When we are trying to use ANDI tool for checking the accessibility issue for ngx-contextmenu, we are seeing the error the below error
[Element referenced by [aria-labelledby] with [id=menubutton] not found.]. This is happening because aria-labelledby="menubutton" doesn't exist anywhere.
To Reproduce

1. Go to https://perfectmemory.github.io/ngx-contextmenu/iframe.html?args=&globals=backgrounds.grid:!false;backgrounds.value:!hex(F8F8F8)&id=context-menu-demo--demo&viewMode=story
2. Right Click on the text to see the context menu
3. Open developer tool or use ANDI tool
4. See the below

Hi @isaacplmann,

I did hear this repo is not getting maintained currently. If this is the case, I really would request you to please have a look on my issue and confirm if this issue can be handled by our end. We are really dependent on this ngx-contextmenu and I would really appreciate your effort on creating such incredible library. Thank you so much.
