Oauth 2.0 api deprecation? (Tab SSO MSTeams Client)

My team got a bizarre email today about a deprecated OAuth api:

Required action
To avoid service disruptions, update your AppSource app before August 20, 2021, to no longer use any of the listed OAuth2 API functions. Instead, we recommend that you use this function:

AcquireTokenByAuthorizationCode(ClientId: Text; ClientSecret: Text; OAuthAuthorityUrl: Text; RedirectURL: Text; Scopes: List of [Text]; PromptInteraction: Enum "Prompt Interaction"; var AccessToken: Text; var AuthCodeErr: Text)

I want to know if my service that utilizes the tab SSO will be affected by this deprecation at all we use client sdk version: v1.6.0 or https://statics.teams.cdn.office.net/sdk/**v1.6.0**/js/MicrosoftTeams.min.js.

We user the getAuthToken() Method listed here:

Please let us know!

Tab SSO our service uses: https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/authentication/auth-aad-sso#get-an-access-token-with-graph-permissions
