Is there a way to get the ISSUE KEY from within the page associated with the asset that linked in JIRA-CLOUD?

I have added assets to JIRA-CLOUD using the api,

/rest/assetapi/asset
Now, I have created a custom field named as Assets, where you can search and Link an Asset. After linking the asset, a page will be viewed below the asset as it has been associated with the particular asset by adding an assetPanel in the Atlassian JSON file.

“assetPanels”: [
{
“key”: “key”,
“url”: “/showAssetDetails?appKey={asset.appKey}&originId={asset.originId}&issueKey={issue.key}”,
“name”: {
“value”: “Asset panel”
}
}
],
Now, as I need the Issue ID for acquiring specific details about the asset which has already been stored with the issue properties.

But, I’m not able to get the ISSUE KEY from the URL, therefore I’m not able to get the issue key inside the page associated to the asset!

Is there a way to get the ISSUE KEY from within the page associated with the asset that linked?
