COPR and closed work permit ending

[T21]

Here's my situation: I have got a work permit attached to an employer and it ends mid March. I have a permanent position with this employer. I applied for the PR late 2019 and finally received a notification today in my account saying "your application was approved" - There is "COPR" mention but cant access the document and I did not receive a seperate email with an attached. I am not sure what the next steps are at that stage. AND I have a question: I have my flat in Ontario but currently abroad and working from home like the entire company (the CEO gave his ok). With my work permit ending and the COPR received, can I still work legally for my employer without doing the landing in Canada because of this 3days hotel quarantine rule? I have planned to come back to Canada but later this year because of the pandemic. Thank you very much for your help.
