Being an oppressed nation with the right to the establishment of a Nation State is different from being an Indigenous people. Calling the Palestinians 'Indigenous' is akin to saying the French, British, or German's are an indigenous people - they're not and neither are the people who have become Palestinians.
The right to self determination is not based on the fact of being Indigenous, if it did a lot of nation states would find themselves without a claim to self determination. After all, Canada New Zealand, Australia, the US, Mexico (and most of Latin America) are immigrant nations that while they have within them Indigenous peoples, are not comprised totally of Indigenous peoples and their right to self determination is not tied to being Indigenous.
More problematic is the intellectual dishonesty that lies in suggesting they are like First Nations in Canada.
"I don't believe the Palestinian peoples have ever approach the UN to be included in the Declaration of Indigenous Peoples."
Unless I'm mistaken, UNDIP doesn't specify 'who' or have a list of those that are 'included'.
And yet, contrary to what you write, they are indeed recognized as Indigenous, as they are, ipso facto, the Indigenous people of Palestine: https://www.un.org/unispal/document/auto-insert-204352/

Furthermore, it's a kind of Pretendianism.
