The icon displayed in the toast message is the icon of the app. To change it you need to change the icon of your app. There is no documented way to have the text only without the icon.

Update: it stopped working the next day :(
In all likelihood, this is an Android 12 bug because immediately after reboot everything works. But as soon as you change the build variants (from debug to release, for example), everything stops working.
And in the logcat I get the following error messages (while I'm trying to show only one Toast, I specifically double-checked):

Original answer
This combination worked for me:
1. Add android:roundIcon to manifest.
<application
...
android:icon="@mipmap/ic_launcher"
android:roundIcon="@mipmap/ic_launcher_round">
Round icon can be generated in Android Studio: Image Asset -> Launcher Icons (Adaptive and Legacy) -> Options -> Round Icon (API = 25) -> Generate: Yes
Also, if it's important, my icon asset is in PNG format.
2. Reboot the device.
After this, my app icon began to appear in Toast messages.
POCO X3 NFC, MIUI Global 14.0.2, Android 12.

public void CustomToast(Context context,String text,int ico,int duration)
{
//define new Toast Object
Toast toast = new Toast(context.getApplicationContext());
//create TextView Object to set icon for it
TextView tv_toast=new TextView(context);
//get text from parameter for toast
tv_toast.setText(text);
//set background color and radius for my toast
GradientDrawable gd = new GradientDrawable();
gd.setColor(Color.GRAY);
gd.setCornerRadius(20);
gd.setStroke(1, 0xFF000000);
//applying setting to tv
tv_toast.setBackground(gd);
//set icon
tv_toast.setCompoundDrawablesWithIntrinsicBounds(ico, 0, 0, 0);
//set duration
toast.setDuration(duration);
//ending- set my custom style for toast object
toast.setView(tv_toast);
// then show it
toast.show();
}

From me the restart of the phone work as well. The toasts now show the proper App Icon, configured in my apps. If it does not work for you please review this statement and check if everything is properly set for you app icon. I hope that this will help :) https://developer.android.com/studio/write/image-asset-studio
PS: There is one more place from which you can build your app icons https://romannurik.github.io/AndroidAssetStudio/index.html

For me a simple restart of the device did the trick.
I had not restarted my test phone after the update to Android 12 at all. I experienced the same odd bug that a generic app icon was shown in Toasts issued by my app. I tried changing the Manifest as Mickaël‘s answer suggested. No luck. I ended up with the exact same Manifest the app had before I started debugging … and then I restarted the device. My app now displays the correct icon in Toasts reliably. What happened? Unsure. I suspect that a restart may trigger an icon cache refresh that crawls all installed apps in search for new/updated app icons.

After running a few tests, I found that setting <application android:icon="@drawable/ic_stat_name" ... with a drawable generated with Image Asset > Notification Icons is overriding the default toast icon.
However, this doesn't work with a drawable generated as Image Asset > Launcher Icons. So at this point, I guess something is missing in Android Studio's generation tool.
