TypeError: Cannot read properties of undefined (reading 'runtime')

Question

I just upgraded to Google Chrome 100.0.4896.127 and I'm seeing the following error in my Angular 13 application in the console:

Uncaught TypeError: Cannot read properties of undefined (reading 'runtime')
    at webcontent.js:1:280
    at webcontent.js:2:463
    at webcontent.js:2:467

I don't see this error in any other browser that I use (i.e. Microsoft Edge). What changed for this to appear? I'm not sure how to go about fixing it.

This is what webcontent.js looks like. This is not a script that I made. I'm assuming it's coming from Angular.

'use strict';
(function(d) {
    (function() {
        function e(a, b) {
            switch (a) {
            case "SCRIPT":
                return `<${a}>function sef() { ${b} }</${a}>`;
            case "PHONENUMBER":
                return b.match(/((?!-)\+?(?:[0-9\(\)\/-](?!\/)(?!\n)\s?){7,19}[0-9])(?=\s|\.|;|'|"|\n|$)/g)
            }
            return null
        }
        const c = d.SEFAgent.browserObject.runtime.connect({
            name: "webcontent"
        })
          , f = d.SEFAgent;
        class k {
            constructor(a=!1) {
                this.set = a ? new WeakSet : new Set
            }
            dedup(a) {
                if (this.set.has(a))
                    return !1;
                this.set.add(a);
                return !0
            }
        }
        const g = f.observerManager.CreateObserver((a,b)=>{
            c && c.postMessage({
                type: "script",
                buffer: e(b.target.nodeName, b.target.textContent)
            })
        }
        , {
            parent: {
                include: ["SCRIPT"]
            }
        })
          , l = new k
          , h = f.observerManager.CreateObserver(a=>{
            c && (a = e("PHONENUMBER", a.textContent)) && (a = a.filter(a=>l.dedup(a)),
            0 < a.length && c.postMessage({
                type: "phonenumber",
                buffer: a
            }))
        }
        , {
            parent: {
                exclude: ["SCRIPT", "STYLE", "NOSCRIPT"]
            },
            node: {
                include: ["#text", "DIV"]
            }
        });
        c.onMessage.addListener(a=>{
            switch (a.type) {
            case "stop":
                g.Stop(),
                h.Stop()
            }
        }
        );
        g.Start();
        h.Start()
    }
    )()
}
)(this);

The error is coming from this line d.SEFAgent.browserObject.runtime.connect. I can't upgrade or downgrade the Chrome version. It's managed by my company. Any help would be appreciated!
