Where I can get, Please use the .deb package to install Network Displays
I apologize... Apparently there is not a .deb package for it... I just looked:
https://pkgs.org/download/gnome-network-displays
Very well...
We can do it the old fashioned way:
Install necessary packages and dependencies:
sudo apt install ubuntu-restricted-extras python3-pip gettext appstream-util cmake libgtk-3-dev libnm-dev libpulse-dev nasm git gstreamer1.0-plugins-bad libgstreamer-plugins-base1.0-dev libgstrtspserver-1.0-dev
sudo pip3 install meson ninja
Make a new folder to hold your download and install:
mkdir ~/src && cd $HOME/src
git clone https://github.com/cisco/openh264 && cd openh264
make
sudo make install
cd ..
git clone https://github.com/benzea/gnome-network-displays && cd gnome-network-displays
meson build
cd build
ninja
sudo meson install
Assign permissions:
pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY NETWORK_DISPLAYS_H264_ENC=openh264enc /usr/local/bin/gnome-network-displays &

In that case, we have tried all I can think of Zorin OS side. I can only suggest you make a bug report with the Developer:

Is there any alternative app for this bro
I do not know enough about alternatives to make a sound recommendation. You might do a net search and read the reviews on each application.
Bro I have searched in Internet but there are no proper results. 
No solution for this
Perhaps @StarTreker on here can help. The Treker has connected TV to Zorin OS successfully in the past.
Thank you, bro, excellent support from your side I'm happy about that.
