Can I use 1Password on Windows 10 without using the 1Password browser extension on Google Chrome?

I have Microsoft Edge but do not use it as my default browser. I want to keep LastPass on my Google Chrome browser until I decide for to quit LastPass and only use 1 Password after I have imported my data and organized it within 1Password.
QUESTION: Can I use the 1Password extension on Microsoft Edge to autofill the websites until I am satisfied that everything works on 1Password?

QUESTION: Can I simultaneously use continue to use the LastPass extension on Google Chrome (without interfering with 1Password) until I make a decision to disable it and use only 1Password?
QUESTION: I prefer Google Chrome over Microsoft Edge when possible. If I make the decision to use only 1 Password can I then install the 1Password extension on Google Chrome, disable it on Microsoft Edge, and begin using 1Password only on the Google Chrome extension to autofill and save new logins (after disabling the LastPass extension on Google Chrome)?

Thanks. james1964.
