Favicon in Joomla 4.03

Hi
I have a little problem

Template Creator CK Version 5.0.6 Joomla 4.03 > Page > system images > Favicon (used in the browser) = Can't see the file with the extension ".ico "

Template Creator CK Version 5.0.6 Joomla Joomla! 3.9.12
Template Creator CK Version 5.0.6 Joomla 4.03 > Page > system images > Favicon (used in the browser) = I see a file with the extension .ico ".ico "

Hi
after checking, I think that the problem is related to the media manager,
in Joomla 4 I use the native joomla media manager
in Joomla 3 I use my own media manager

in joomla 4 you can change that in the media manager > options > Legal Image Extensions (File Types) >> add "ico"

CEd

you can change that in the media manager > options > Legal Image Extensions (File Types) >> add "ico"

It works . Thank you very much for your help
