iPhone 13 Pro Red warning mark on Messages icon

[iphonefreak450]

Just received my iPhone 13 Pro and I set it up as a New Device. Nothing else.
Once the phone booted to the home page, there is a warning mark on the Messages app.
Here is what I tried below.

-Turned iMessage ON/OFF (Seen my phone number registered) and my Apple ID email as well
-Signed into my Apple ID/iCloud account. Then Signed Out of my account. After that, same issue. Still the red mark.

Still the same issue.

Does this mean that I always need to be signed in to my Apple ID account to remove that warning mark?
I do not want to use iMessage because most of my friends use Android phones and also, when I go out, I do not have cellular internet. Only WIFI when I am at home.

Update: In the iMessage settings, I only removed my number and left my Apple ID email only. Now, no red mark. I also needed to update the phone to 15.4 and restarted the phone.

Then, I Signed Out from my Apple ID. No red mark.

In the future, the only way to remove this red warning mark is to first sign in to my Apple ID or toggling On/Off iMessage?

Please explain.

 

[now i see it]

iPhone will forever pester a person to sign the phone into iCloud if it is not.

Suppose I decide to get a new iPhone in the future and setting it up as a new device, I should then sign into my Apple ID and then sign out again in order to remove that red warning mark over the Messages app?

Because I never put anything on iCloud and never even plan on using it.

Also, should I just turn On and Off iMessage as well?

Please explain the steps on what to do in case I get a new iPhone.

Blue bubbles on 24/7, that's if you want to send/receive full quality images and videos.

Them green bubbles hurt my eyes, hope apple make the green bubbles a darker shade, wonder which genius at apple thought white text with a light green background was a good idea. ?

Just wanted to know how can I remove the ❗️on the Message app? And also, I don’t use iMessage either because when I’m out on the road, I don’t have internet, only WiFi.

Now there is no ❗️over the Message app. But for next time when setting up a new iPhone, how can I remove that?

Set the display to "Increase Contrast" in Accessibility...the annoying light green becomes dark green so it's much easier to read
