What connection type is used for "Accountable" in RACI chart with EPC model?

I am setting up models/objects/connections to fully support the RACI chart in ARIS Connect; and I want to make sure I am using the correct Role-to-Activity connection to represent Accountable.  I can probably figure this out by trial and error, but it would be a lot quicker if someone can tell me!  :-)

What is the connection type, to be used in EPC models, between Role/Organizational Unit/Position objects and Activities, that is shown as "A" in the standard/default RACI chart in ARIS Connect?

thanks in advance
