Key-In Double-click to open embedded OLE Excel object

Probably more of a PowerPlatform question but....

Testing an upgrade to OpenBuildings Designer Connect Update 7 from OpenBuildings Designer Connect Update 3

...in Update 3 we had a custom ribbon button that invoked the following key-in

powerselector mode new;powerselector single;choose element;xy=-0.1583,-0.0354;xy=-0.1583,-0.0354

which simulated a double click on an embedded Excel OLE object and resulted in opening the embedded Excel spreadsheet in Excel. The coordinates displayed represent the low range bottom corner of the OLE Object. 

after moving our custom ribbon button into Update 7 it is no longer working and neither is trying to perform this via the key-in dialog. However if we double-click via the mouse the OLE object it opens just fine. I have included a small mp4 displaying the behavior in Update 3

Is there a new way for me to key-in a double-click?

Thanks in advance
