What is the tiny transparent dot about?

[MehradThe1st]

I've seen this dot only in my recent phones with android 10, It sometimes appears out of nowhere and disappears randomly, Tho it's extremely rare, At least for me, In the year and a half that I used my last phone (Honor 9X Global EMUI 10.0 Android 10) I've seen it only once, And just yesterday I saw it again for the first time on my new phone (Huawei Nova 7i/Nova 6 se/P40 Lite EMUI 10.1 Android 10)
Honor 9X:

Nova:

I wonder if it's something like the iPhone's indicator telling you when an app is using the camera or mic? https://support.apple.com/en-us/HT211876
