We are developing a mobile app, which our customer requested the following login/registration options.

Email, Gmail, Apple, Phone

In addition to that, customer want the user to try the app before they register.

Our UI/UX designers are not very happy about this, because they say they have never seen an app using both Email/Phone and it is very hard for them to create a good user experience on this.

For an example, they say if this app is using Email, GMail, Apple for login, then they can create Email/Password fields and place Gmail, Apple icons below this. But when the phone number comes in, they question me where on earth they can place it without creating a bad experience.

However customer is strict with his Phone login requirement. But if this "really" should not be done, I can convince him.

This is a Freelancing app.

I am looking for your advice on this, whether this Email, Gmail, Apple, Phone approach is good or we should remove phone or email.

Your UI/UX designers are on the right track with placing the SSO buttons outside of the main login.

To add mobile and keep the UI from getting too cluttered, you could move the Password field to the next step (like Google does today).

Login UI that supports email, mobile, and SSO

If the user enters a phone number, they wouldn't go to the Password step; they'd instead see a step to enter the code that was sent by SMS, or however you plan to complete the authentication.
