yesterday release of bot composer 1.3.0 is done due to which few things have changed
some basic information: i was trying to export a skill bot and connect to that bot within another bot 
by following documentation https://docs.microsoft.com/en-us/composer/how-to-export-a-skill.
Problem: how to connect to a skill and how to use skill host end points  for local testing with the recent changes? documentation is not updated and it seems it takes time.
 
Steps to Reproduce issue:
i have created 2 bots and generated manifest for skill bot and tried to use it in the consumer bot 
with recent changes i don't find any place where i could use skill manifest json of a bot  as a skill in any  consumer bot.
documentation https://docs.microsoft.com/en-us/composer/how-to-connect-to-a-skill  says : Still on the Skills page, select + Connect to a new skill on the upper left corner of the toolbar to show the Add a skill windows."
now the problem is how to move forward from this step within bot composer 1.3.0?  i am unable to select " skill dialog name" and  "skill end point".

Changes observed : 
1)skill host endpoint  previously used to be like  http://localhost:3983/api/messages now changed to  http://localhost:3980/api/skills
 
2) there used to be a skill section in UI where we can connect to another skill  using skill manifest json file of a sill bot as mentioned in the documentation
https://docs.microsoft.com/en-us/composer/how-to-connect-to-a-skill
QUESTIONS : 
1)as the 1.3.0 release is few hours old  i need some quick guidance  over here how to use a skill bot in another consumer bot.
2)is there any alternative to export skill as a manifest ?  we need some quick solution to this problem
