Expiring AzureAD Client secret with implicit and hybrid flow

Our AzureAD Client secret is going to expire soon and we already created a new client secret but have not deleted the expiring one yet. It is used to authenticate our .Net core Web application.

We store Clientid, TenantId, domain etc. in appsettings.json and authenticate it using OpenIdConnectDefaults.AuthenticationScheme with Microsoft Identity platform (i.e. using .AddMicrosoftIdentityWebApp AzureAD configuration binding). We currently do not hardcode or specify the ClientSecret in our application or using any keyvault storage.

This is the screenshot of our Azure AD authentication set up which uses ID tokens (Implicit and hybrid flows option). It also does not allow public client flow.

If we delete the expiring secret now or let it expire next week, Do we need to make any change in the application or ID tokens (implicit and hybrid flow) option even require a client secret? Kindly appreciate your response.
