I am trying to install the package from paymaya, after adding the package from File > Add Package

it showed:
Paymaya-iOS-SDK-v2.git could not be resolved
~Updating from:
~ package ‘package.swift’ is using tools version 3.1.0 which is no longer supported, consider using ‘//swift-tools-version: 5.10’ to specify the curent tools version

I clicked “add package anyway” and updated clicked ‘Update to Latest Package Versions’. I tried to look for the Package.swift because I want to manually change it to // swift-tools-version:5.10 but I couldn’t find any file.
