Integrate third party API in Angular [closed]

I have one library that gives pharmacy related data and I want to integrate in Angular, they have simple JavaScript code as below:

$('div#rxContainer').WebRefill({
    PharmacyId: "SOMEID",
    PharmacyPhone: '555-555-5555',
    AuthServiceUrl: 'https://auth.apps.scriptpro.com/', // url for authorization service
    RefillServiceUrl: 'https://webrefill.apps.scriptpro.com/', // url for refill service
    PaymentServiceUrl: 'https://payment.apps.scriptpro.com/', // url for payment service
    ColorTheme: {
        TitleBar: '#333300',
        Background: '#D4D5C6',
        BreadCrumb: '#6D6D4A',
        BreadCrumbActive: '#4A4A21',
        MainButton: '#333333',
        SecondaryButton: '#6D6D4B',
        RxContainerHeader: '#6D6D4A',
        RxContainer: '#CD853F',
        Title: '#333300',
        EmphasisText: '#330000'
    }
});

HTML: <div id="rxContainer"></div>

I’ve added required script in index.html file:

<script src="scriptpro/Scripts/ScriptPro.WebRefill.js"></script>

NOTE: “SOMEID” in PharmacyId will be dynamic.

I have tried as below:

HTML: <div id="rxContainer"></div>

.ts file:

const element = document.getElementById('rxContainer');
    if (element) {
        element.innerHTML = 'Content Updated!';
        element.WebRefill({
            PharmacyId: '2215b3ae-3ad7-4c47-9bed-a7da9c4aa561',
            RefillServiceUrl: 'https://webrefill.apps.scriptpro.com/',
            AuthServiceUrl: 'https://auth.apps.scriptpro.com/',
            PaymentServiceUrl: 'https://payment.apps.scriptpro.com/',
            ColorTheme: {
                TitleBar: '#333300',
                Background: '#D4D5C6',
                BreadCrumb: '#6D6D4A',
                BreadCrumbActive: '#4A4A21',
                MainButton: '#33333',
                SecondaryButton: '#6D6D4B',
                RxContainerHeader: '#6D6D4A',
                RxContainer: '#CD853F',
                Title: '#333300',
                EmphasisText: '#33000'
            }
        });
        this.cdRef.detectChanges();
    }

But it shows an error

Property ‘WebRefill’ does not exist on type ‘HTMLElement’.
