How changes Breadcrumb add, share, remove buttons

Hi

Where and how do I change the add, share and remove buttons in the breadcrumb menu.

I don't want to remove the breadcrumb in sub_footer.html. I have double share buttons and need to remove one of them.

And how can I disable them for not logged in users?
It's in Dolphin 7.2.1 

Regards

I guess no one is available to assist you. or were you assisted offline?

No

I solved it by myself. 

 Would you share the solution, please?

Perhaps others have the same question and would benefit from knowing how you fixed it. :)

Typical response to a reasonable request from @sbg101.

You did well to dig this one up. I thought I was going way back on catch-up.
