Token expiring in Power BI embedded (error 403)

Hello community. We are trying to embed a Power BI report using the ReactJS framework and npm installator with the following configuration:

<Report
      

      

        tokenType="Aad"
      

      

        accessToken="H4s...sc2V9fQ=="
      

      

        embedUrl="https://app.powerbi.com/reportEmbed?reportId=6300f419-XXXX-XXXX-a55e-723f417a3f2b"
      

      

        embedId="6300f419-XXXX-XXXX-a55e-723f417a3f2b"
      

      

        reportMode="View"
      

      

        datasetId={datasetId}
      

      

        groupId={groupId}
      

      

        extraSettings={extraSettings}
      

      

        permissions="View"
      

      

        style={reportStyle}
      

      

        />
      

     
      

   Where datasetId and group Id are delared in the extraSettings as follows:

 const extraSettings = {
        

        

          filterPaneEnabled: false,
        

        

          navContentPaneEnabled: false,
        

        

          hideErrors: false
        

        

         };
        

 The problem is that, althout it initially works fine, after a while I get a error 403 when loading the report. I obtained the accessToken via postman and also using this post  

https://api.powerbi.com/v1.0/myorg/GenerateToken in the documentation located at

https://docs.microsoft.com/en-us/rest/api/power-bi/embedtoken/generatetoken#code-try-0

Is it possible to create some sort of API inside mi project to automatically generate an accessToken, with the Power BI Bearer Token as it expires?

Thanks in advance for your help.
