How to remove Play protection notification?

Question

Android

Hello.
Wrote an application. Created and signed apk.
I install this apk and get a warning from Google protect
"Play Protection could not find information about the developer ..."
After googling, I tried different options to remove this notification:
created a new keystore, filled in all keystore fields,
increased the validation period to 50 years, tried and debug and release versions, just not signed apk ... does not help. All the same, this warning pops up.
Does anyone have any thoughts on how to remove it (respectively, without turning off protect)?
PS
Application for a small circle of people, I would not want to contact Google Play
PPS
Another thought arose, this is a warning that there is no information about the developer.
That is, if I place an application on Google Play and sign my main application
with the same key, will it disappear?

"That is, if I place an application on Google Play and sign my main application
