I am using Group module and Drupal 8.
After adding a new group, the page will be redirected to the corresponding group page(ie. /group/5) but I want to change it to be the group edit page (ie. /group/5/edit)
After relating/creating an entity in group, the page will be redirected to the gnode page (ie. /group/5/content/116) but I want to change it to be the group content page (ie. /group/5/content)
I have read this issue but I want to solve this problem using either installing modules or creating a custom module.
I am new to Drupal and programming so it is great to have some clear and complete elaboration.
