Paste screenshot into rich text editor field into sharepoint list multiline field

I have couple of multi line (enhance rich text) field in sharepoint list ,
I have refer a video of Shane which converts b64 into binary .
Most of the part is done , the only place I'm facing problem is

With({varHTMLTableInhalts:Split(RichTextEditor3.HtmlText,"<img")},

If(CountRows(varHTMLTableInhalts)>1,

With({varB64start:Find("<img",RichTextEditor3.HtmlText)+33},

With({varB64End:Find("""",Mid(RichTextEditor3.HtmlText,varB64start))-1},

With({varFileLink:B64ToBinary.Run("Paste" &Text(Now(),"dd/mm/yyyy")&".png",Mid(RichTextEditor3.HtmlText,varB64start,varB64End)).biinaryoutput},

Set(varInhalt,"<div>"& Replace(RichTextEditor3.HtmlText,varB64start-22,varB64End+22,varFileLink)&"</div>")))),Set(varInhalt,RichTextEditor3.HtmlText))))

Patch(XYZ,Thisrecord,{Multiline field : varInhalt});

So my field value is <div><img src="https://abc.com/sites/APE/RichImage/Paste09_07_2024.png" /></p></div>

This value is not converted into html code rather string value.
When I'm passing <div><img src="https://abc.com/sites/APE/RichImage/Paste09_07_2024.png" /></p></div> its getting converted as <div><img............... while viewing the record.
Please help how can I go ahead with it.
