While you are live in Loola, search for your username in the TikTok search, or, click a previous TikTok post. You will see a red ring around your profile image with the text "live". Click it and you will get into your live.
​

Note: the red ring does not show in your own profile page, only in video posts and search results.

In order to see yourself live in Instagram while using Loola, you will have to login to Instagram from a different account.
Once logged in under a different account in the Instagram mobile app, you could view your real account just like your followers do.
