Hi @cindelwood,
Do you already have a flow setup? If so, can you share a screenshot?
What you could do is use a For a selected item trigger action. That action will only return a couple of properties of the item. With a Get Item you could retrieve the rest of the columns like Facilitator. After that you should be able to see/use the Facilitator Email column from the Dynamic content list.
Below is an example of that approach.
1. The flow setup.

2. The formatting of the Send Request column
{
"$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
"elmType": "button",
"customRowAction": {
"action": "executeFlow",
"actionParams": "{\"id\":\"yourflowid\", \"headerText\":\"Example E-mail Template\",\"runFlowButtonText\":\"Send E-mail\"}"
},
"attributes": {
"class": "ms-fontColor-themePrimary ms-fontColor-themeDark--hover",
"title": "Launch Flow"
},
"style": {
"border": "none",
"background-color": "transparent",
"cursor": "pointer"
},
"children": [
{
"elmType": "span",
"attributes": {
"iconName": "Mail"
}
}
]
}
