In Angular 14, how do I compare an enum value within a component's HTML?

I'm using Angular 14. I have an enum ...

export enum MyEnum {
    First,
    Second
}

then I hvae an object that declares one of its fields to be that enum

export class MyModel {
    ...
        myField !: MyEnum;
    ...

In a component, I want to check if the field matches a particular enum value, so I tried

<span *ngIf="!myObj || myObj.myField != 'Second'" class="p-float-label">

but this results in the compilation error

error TS2367: This condition will always return 'true' since the types 'MyEnum' and 'string' have no overlap.

What's the proper way to compare an enum value?
