how can I open editor programmatically in Capella using the activity link

Dear all,
I have created a section with one activity in one of the capella activity explorer pages (Physical architecture) and all I want is to open the editor when the link of the activity is pressed.
I am trying to use the sirius method: but it seems that some plugins in the capella studio recent versions (
1.4 & 1.3) generated stubs are missing like
org.eclipse.sirius.ui and
org.polarsys.capella.common.helpers and other dependent plugins.
So is there any sophisticated way to open the editor using capella plugins since the sirius plugins are not included in the generated folders like activity explorer?
